There is a white list of users that we can add you to so you don’t have to worry about ever getting banned again so a false positive should only ever happen once. I see you are now on that list so it shouldn’t happen again (If you do get banned again definitely let support know because that means it isn’t working as it should).
The history of all this is that the site was targeted by a bot farm that was automatically creating accounts and, probably using llm based agents, bombarding the site with vandalism faster than we could clean things up (picture hundreds of theory tabs with titles trying to sell viagra and financial scams). We’ve noticed that the bots still probe things every once in a while for weaknesses. They were relentless and very smart about avoiding all other things we set up (different IP address, getting around specific word based filters by using llms to change wording slightly over and over and over again as we reacted in real time. It wasn’t a fun couple of days).
There aren’t that many real people trying to create theory tabs so we think the best way is to use white lists plus a filter.
It’s a tough ask for this spam filter though because the edit comments plus title/artist are often only a few words which don’t look like a meaningful content sometimes. I don’t want to speculate too much, but the name of the song that banned you was “Las Vegas”, which I have a feeling made it think may have been gambling related. 
Anyway, for anyone else who happens to read this. Don’t take it too personally if you get wrongfully banned. If you are contributing to theory tabs a lot it should only ever happen once, at which point you can get whitelisted by a human.
