As he said, modlogs are public, and it seems like other user retreived the trace of what you call an “abuse of power” : https://sopuli.xyz/comment/12732467 .
It is in his right as a moderator to chose how he moderate the communities he has the right to. If he finds your comment pedantic and annoying, and chose to remove it, so be it.
I’m not taking sides here. I don’t know the whole story, and I doubt anyone else here does. With the little context provided, It’d be hard to take knowingly a side.
But in both case, this is textbook harassement as you are copy-pasting this comment on every community this is posted on. This community has a pretty clear rule against harrassement (rule 2), which you are breaching, offense for which I’ll use my g… mod given right of banning you for the time being (for at most 30 days, I’ll re-evaluate tomorrow when I’ll be less tired).
Remember to put anything from an unknown Google Drive through a propper virus check. No offense OP 😉.
