You asked for a screenshot, but I don't have any screenshot because none of them shared any screenshot. But, I know at least two of my local forum members who's telegram account was banned even though their account was registered with a original local phone number. I know another pakistani forum member who's account was banned but we was able to unban his account again.
So, from the previous post where there were many people who got their accounts banned, we are now down to two Pakistani users who were banned, plus one more who later got unbanned. Is the claim still that many people are getting banned or perhaps that some are?
It would be interesting to check what those people used their accounts for, what kind of groups they were part of, and what they were posting, sharing, forwarding, etc. It's always possible that innocent people get caught in a wider ring with those who misuse a service and use it to spam and scam. But as you mentioned yourself, they can get unbanned assuming they didn't do anything wrong.
It's always the same with centralized and custodial services. You can either play by their rules or go elsewhere.
