Why do contributors delete their own posts?


A significant contributor who shall remain unidentified deletes posts shortly afterwards. It’s not done with the intent of correction, but for the purpose of limited viewing. I wonder what rationale warrants this behavior. It certainly not for the benefit of providing context for later viewers who might want to learn from the thread.

TBF, I delete posts when I've said something which was clearly wrong, but when I wrote it I was short on coffee, but it is too late to edit it.


I've also deleted an entire thread out of an abundance of caution that I might have used a phrase which would be misconstrued to support or approve of antisemitism and that is never my intention.

Best,

Criteria? How about it looks like a troll, it walks like a troll and it talks like a troll?
