In a time where twitch is evolving and changing a lot from its initial standpoint, I would say we could benefit from a little consistency and pride.
Therefor my suggestion is loyalty badges - as in years you have been on twitch.
This would mean after year 1, 2, 5, 10 you would have a badge you can choose to have in chat to show that you have been a part of twitch for x amount of time and isn’t a new spam account fx. - but someone who loves and cares for twitch.
Steam has it fx. so I see no reason it couldnt work here.

Brainstorm: Heck I even think down the road it could have certain perks/applications where youd fx. couldnt apply as a mod in channels unless you been on twitch for say 2 years etc. (just brainstorming)

TL;dr - Loyalty badges that show for how long your account has been on twitch to create some consistency
