Interesting story how that ISP complaint was taken so seriously and police were actually involved.
Hopefully it can be an example, be it extreme, for anyone to tread lightly online as well as in real life. Take a breather. Life is short. Don't get to worked up. Yes, private forums can have their own rules, but moderating should be done in moderation
and with skill. I've been an admin & moderator before. It can be tough. Opinions differ. Can't let stuff escalate. And, misunderstandings are easy. Almost 20 years ago I got instant-banned from an international chat server I'd been visiting and making online friends; when I simply and innocently asked one night if anybody else was constantly getting unwanted messages in Spanish. Spam from before spam was coined.
Long story. I was new to the internet at the time. My English wasn't that great. I had joined this group. Made friends. Everything was great. Except for one thing. I kept getting these direct messages in Spanish! Even if I understood what they were about, I wasn't interested in them, couldn't figure out how to stop them, and they just kept coming. So, being that it was a friendly place, I just asked in the chatroom if the same thing happened to other people. BANNED! (no warning) Instead of the owner/admin asking clarification about my issue; recognizing a new user may have some technicality/preference setting or - you know - stop some individual(s) from spamming everybody else; he instantly banned me due to racism (violation of TOS). I couldn't utter a second line. There was not an iota of truth to that claim about racism, because I even had friends in Spain, and I would have asked the exact same question if the messages were in English, French, Dutch, German, ... - except this spam was always in Spanish, so I included that when I politely and innocently asked if anybody else was getting unwanted messages. As far as I know a complete misunderstanding. The guy who banned me wouldn't hear it. No defense. No exception. TOS. Guilty until proven innocent ... For basically using the name of a language along with unwanted messages. I was not ranting against this or that, using whatever derogatory language or what have you, making off base remarks, jokes in poor taste. None of that.
I did get several online friends to vouch for me and was let back in a while later, but despite my apologies for the misunderstanding, never got an apology that it was an overreaction on the other end. I thought that was pretty low the guy couldn't man up.
Anyhow. It was a pretty frustrating and interesting experience back in the day, where somebody decides to cut you off from your online friends for basically nothing.
All I can say is, apologize and avoid other stepping on another toe. Or move on.
