Are you actually just finding out that when you use centralized exchanges you should expect things such as this?
No)) of course I have known about this for a long time.
Your blacklist or whatever doesn't help in anyway. It is no longer news that centralized exchanges can make arbitrary decisions at absolutely anytime.
There is no specific list with a concise listing of exchanges so that a regular new user can come in and get acquainted. So that in 5-10 years a new user coming to the cryptosphere can open the list and find out which exchanges and services he should not use.
