We're not talking about a thread or post in conflict (or at least I'm not).
When there's an issue with admin about a post, admin PMs you personally about it, and what steps were taken if it's removed. If it's edited, that shows on the post in public, or if the thread is locked, that also shows. If a thread is deleted, well then the whole thing is gone, not just my postings.
I do know that in long times past there was someone on the site "team" who removed old, outdated posts or threads. (Such as one announcing an upcoming event that would now be long past, etc.) I have been assured that no relevant posts are being removed.
I thought about noting the actual post #, but only see that when I do a search, and not right after I post. But that's what I'll go hunt next, so I can actually note the post #. Actually, I think I did do that recently and when I went back to the thread, someone else's post, which would have been right after mine, had that number.
I'm ok. I long ago realized nothing I say is that important!
