Update 2024:

"Verification Law: All sub-laws have been moved to this law category; has been added to New Horizens Nation:

New Horizens Nation Soil

All these Americas, Asia, Africa, Europe.

Amazon and Twitch Staff were contacted multiple times.

There is a Recording of Executive officers refusing to acknowledge the public annexed their business HQ countries without their vote.

Twitch and Amazon now belong to New Horizens Division,

This is a direct quote from their board of directors,
"We apologize if any New Horizens Laws were broken,
We do no wish to fire, remove, or punish Executives types for their lack of knowledge, not every person receives direct communication from NHN leadership. Most major News and Information providers have owners who despise utopian systems
(USALLY BECAUSE IT RESTRICTS THEIR ABILITY TO MAKE 13K$ A MINUTE.)

Therefore will never actually cover news on them.
There are many laws , and countries you've never heard of because of how information providers work in the old world order.

We stand by our C.O.O. unfortunately all the ex-executives, managers, and owners fail to, and refuse to accept our authority or the fact they have been let go due to their failure to provide acceptable service provision to the people."

We stand by new Horizens Division.

as for 2fA. all companies regardless of a real country or perceived country... do have to follow New Horizens Nation Law for all of our listed soils, when provides goods, products, services to and or on our soils.

Our soil is entire 16- 125 years on Earth (in Earth's orbit too) people voted by modern means. circa 2012 and up
so if you would like to debate our results you will have to compile every in-person protest, riot civil war, etc. every single public social media post and comment in which a user has described our infrastructure/ leadership.

because 9/10 we are the only government and country that has both infrastructure and leadership described in the posts.

but good luck with that because without supercomputers, Fantastic coders at your disposal and a direct line to The registered 2022 Information provider.
It should only take you 6-10 years to do so.

Because only the first 14 pages of our DOI/CBOR Have actually been published online. there are currently 32, all in Picture Exchange Communication format recode...

The 2024 changes to entire new continents added due to 2020 posts being recompiled at the end of 2023. have not been published."

~signed the 2023 NHN R/A LSC~

its a direct statement from the government...
twitch still has not update their 2fa. also sorry I'm a long winded poster

UNFORTUNATELY, THE PEOPLE WHO RUN THE PHONE VERIFICATION ARE VERY CLASSIST AND ELITIST (AND HAVE THE MONEY TO BE ABLE TO TIE JUDGES UP IN COURTS FOR YEARS TO GET AWAY WITH IT)

EVEN THOUGH WORLD LAW

, THE NATION TWITCHS MAIN HQ NOW RESIDES IN BY (84% IN-PERSON ANNEXED PROTEST VOTE, IGNORED BY GOVERNMENT AND INFORMATION PROVIDERS ( MOST OF THE VOTES WERE LABELED AS RIOTS OR ATTACKS), { EVEN WHEN N.H.N FEDERAL JUDGES/PRESIDENTIAL CABINET MEMBERS POST/ COMMENT ETC, THEIR POSTS ARE REMOVED. WHICH BY THE WAY IS ACTUALLY AGAINST THE LAW OF THIS NATION, IT MEANS IMMEDIATE SEIZURES OF A COMPANY)

AND NATIONS OF THE WORLD

ALL HAVE THE FOLLOWING LAWS IN PLACE
1: GOOGLE VOICE IS CLASSIFIED AS A VALID VOIP CELLPHONE SERVICE
2: PREPAID CELL PHONES DO REQUIRE A VALID AND REAL IDENTITY TO BUY AND USE: SO THEY ARE CLASSIFIED AS CELL PHONES

3: ALL SERVICE PROVIDERS LABELED WIRELESS CARRIERS BY YOUR NATIONS FCC(AKA OTHER NAMES) HAVE TO BE INCLUDED IN PHONE VERIFICATION, THIS INCLUDES PREPAID AND VOIP SERVICES THAT REQUIRE YOU TO PROVIDE A REAL IDENTITY TO USE.

4: IN NEW HORIZENS NATION
THEY HAVE AN IRONCLAD WAY TO PREVENT PROVIDERS ELITISM/ CLASSISM/ PAY CHECK SERVICE PROVISION DISCRIMINATION( ex: THE ACTUALLY REGULATE BUSINESS PRICING:

IN 2012-2016 NEW HORIZENS NATION,
THEY LABELED ALL OF THE WORLD'S DISABLED, IDENTIFYING
THEM SELFS LBGTQ+, PEOPLE WHO HAVE SPENT OVER 50+ YEARS ON OR IN EARTHS ORBIT AS PRIMARY CITIZENS ( WHY BY THE WAY = 50% OF THE WORLD POPULATION)

SINCE WORLD GOVERNMENT LAW PREVENTS DISCRIMINATION IN THESE CATEGORIES( NOT ALWAYS ENFORCED BY INTERPOL IN CERTAIN NATIONS)
CEOS AND BOARDS OF DIRECTORS HAVE TO FOLLOW N.H.N LAW
WHETHER OR NOT THEY AGREE WITH IT, THEY CAN LOSE THEIR COMPANY IF THEY REFUSE.

oh AND a FEDERAL JUDGE WHO IS A PART OF THE N.H.N
THE PRESIDENTIAL CABINET ALREADY CONTACTED TWITCH STAFF
BECAUSE GUESS WHAT THEY ALSO STREAM( IT IS ACTUALLY PART OF THEIR PRESIDENTIAL CABINET DUTIES( ALONG WITH MAKEING SURE the PRESIDENTIAL CABINET IS ALWAYS FOLLOWING THE #1 LAW FOR THE PEOPLE BY THE PEOPLE: BEST POSSIBLE SOLUTION IMPLEMENTED REGARDLESS OF COST.
UNFORTUNATELY FOR TWITCH USERS MOST OF THE EXECUTIVE STAFF AT AMAZON WERE NOT AMONG THE INDIVIDUALS WHO JOINED THE MASS PROTEST. mOST OF THE STREAMERS WHO LIVE STREAMED THESE ANNEXATIONS/PROTEST. REQUESTS.
FOR NEW NATIONS AND LEADERSHIP GET PUT IN TWITCH JAIL.

WORLD GOVERNMENT DECISION AFTER WORLD WAR 2:
IF THE PEOPLE STATE AT ANY TIME "WE WANT A NEW NATION & LEADERS THAT WILL GIVE US THE INFRASTRUCTURE AND RIGHTS WE DEMAND"

ANY EXISTING NATION OR BUDDING NATION CAN ACCEPT THOSE PEOPLE AS CITIZENS THIS PROCESS WILL HENCEFORTH BE KNOWN AS DEFECTION, ANNEXATION, OR ASYLUM THE REQUEST MUST EXCEED 64% OF THE KNOWN POPULATION. IF THE NATION LEADERS REFUSE THIS WILL BE KNOWN AS TYRANNY AND APPROPRIATE ACTION BY INTERPOL AND OTHER NATIONS. WORLD LAWS ARE NOT WELL KNOWN BY MOST FORTUNE 500/100/50 OR EVEN FORTUNE 10 LAWYERS. LOL SORR FOR THE LONG COMMENT

A google voice number is what I've been using since 2011 as my phone number along with a data only plan, this is very frustrating to me. It's let me have the same number inside and outside of the US when traveling and I appreciated that.

Google Voice actually doesn't let you get new numbers that easily and I think that this is a really helpful change to make.

I've had several very poor members of my community that do not have any phone at all and use Google Voice as their only communication method for calls and texts that I have had to tell, I am so sorry but I simply need to protect my community from hate raids and the like too much to not turn on the safety measures I can. I have changed some settings to be more lax, but sadly I cannot make them all lax ENOUGH to get everyone who is too poor to own a cell phone. But I also know what it's like. When I was younger I was too poor to own a cell phone for a while when I was barely surviving. And there's no reason why those people don't deserve to get to still feel a sense of community, be a part of spaces, etc.

Worst case making some kind of "delay" on allowing a Google Voice or other VoIP-based phone number be accepted like you have to set it and not change it for 6 months.

I haven't had a cell phone with a phone number in a decade-plus since getting a Google Voice back when it was still called Grand Central. Haven't changed that number in that entire time, my cell phone just gets data-only SIM plans since I only use it for light browsing and GPS away from home.

Using textnow (with subscription) in order to verify your phone number.

I use Google Voice for all my mobile needs. I give it out to every service that asks for my mobile number, and then, if they give it out to spammers, I can easily filter them out.

But I can't use my GV number for Twitch - it reports "only mobile phone numbers may be used".

I do not give out the number that goes to my SIM card. It's not necessarily going to be the same number if I switch providers, and literally every text and call I get through it and not GV is spam, because I never give it out.

Since people are starting to use "verified accounts only" on their chats, this has suddenly gone from "that's annoying" to "this is preventing me from participating in communities". And I don't think the streamers are wrong for using the filter, because I've watched what happens if they don't, so I'm not going to try and convince them to change it.

Perhaps GV allows you to get new numbers too easily, and all the other services I've used it with such as [checks notes] Amazon Web Services are inundated with people using fake GV numbers.

But I don't think that's the case, presently.
