I kind of get it in cases where no one has commented yet, and the OP realizes a mistake or how stupid a question it is. But once there’s engagement, I wish the OP would leave it up.

I’ve noticed this a lot lately: I’ll comment, my comment will get engagement, so I’ll check the thread again to reply or read other comments, do that, then come back later to follow up again, and it’s all been deleted. Like, even if the original post was stupid or embarrassing, the fact that there was genuine engagement, to me, means it shouldn’t be deleted.

But again, I understand the anxiety of leaving your own stupid words up if they really bother you, so I won’t lose sleep over this.
