Very true, for example in case of reddit shadowbans it is trivial to check if an account is banned while a legitimate user can go on for a very long time assuming that simply no one is replying, unaware that something like a shadowban exists.

They might reach the point where one starts to feel litigious, if one pays for the service and there is anything remotely approaching an SLA. Be careful if you are a paid service and use shadowbans.
