I’m willing to bet this wasn’t the reason that they banned you, rather, you got them upset by having an opinion they didn’t like and speaking it outloud (like, say, saying Israel seems to be carrying out genocide on Palestinians), and they made a note of it so they could ban you in the next window of opportunity. They do this sort of bullshit all the time, sometimes using alts acting like assholes that never get banned no matter how many rules they break to try to rile you up. That way, they basically don’t have to answer to anyone.

I noticed this too, happens if you are not using old.reddit.com and are not logged in.
