verified-only chat can be bypassed by sending a message along with sharing your watching streak
If a channel has verified only chat and stream watching streaks for bonus channel points enabled at the same time, unverified accounts can send a message when sharing their x-streams watching streak.
This potentially allows users (and bots - hence I tried to use the contact form first) to bypass chat restrictions just by waiting a few days/streams.
I would also suggest a real human reviewing cases coming from the "contact us" form. The reply which I never expected to go this way, assumed I want to have my account verified without actually confirming my phone number even though I provided all screenshots for the restricted chat and the fact I was actually able to send the message, lol.
