Yep I see what you're saying.
Other point I wanted to make and forgot to is that we're happy to answer your questions but sometimes it's not possible and we dont have nor need to answer every single thing with details. Some stuff are best kept disclosed for the good of the forum and/or to preserve the banned member's 'dignity'.
hypothetical example: let's say we find out a respected member had a second account that they would use to troll the board every once in a while. If we ban them, we might prefer to not disclose the reason and in this specific case, the banned member wont want to tell anyone why they got banned either (and 9/10 times when asked by other people they'll pretend the ban was uncalled for etc even though they fully know why the call was made).
