I had a similar issue. I had probably two million comment karma spread across about a dozen accounts. My first account was quickly auto-banned from several subreddits as soon as I started editing old comments. Those pro-spez mods had seen what people were doing during the exodus, and set the automod to ban those who tried.
Then I did the same with my second, third, fourth, etc accounts. All of those were immediately site banned for ban evasion, because I was interacting with subs my first account had just been banned in. So none of the edits on those later accounts were pushed through.
Reddit later un-banned those accounts, and all of my old comments were visible again. Likely to make the old comments show up.
Not gonna lie, I was worried your second paragraph was going to turn into Mankind throwing Undertaker off of Hell in a Cell
