Also late to the party but I can definetely say that more than a few of my posts are in fact not mine : this one about falsifying CMD diagnostics and this one about the Finally Awake tournament for starters.
While I’m also racking my brain over the rest of my posting history, the one pattern that does jump out in knowing which posts for sure came from me is when I’ve posted multiple times in a single thread. I am not sure what that means (if anything) but maybe they’re still wary of making us reply to ourselves so they’re sticking to isolated posts that have a better chance of going unnoticed ?
