I put a lot of effort in writing comments in a conversation, arguing against one initial comment made by another user. That user finally deleted her original comment, as well as an ulterior one, rendering the whole conversation meaningless to any other potential reader.
I can understand that one would not like traces of its past errors to remain forever visible on the Internet, but it is obvious that everybody is exposing himself to that when posting on Stack Exchange, and should accept the risk. The conversation was polite and, to my mind, interesting – deleting it does not do any good.
I find it rude and disserving to the community to thus break a whole conversation. My comments now seem to spring out of the blue – you can guess what that makes me sound like.
If the deleted comment doesn’t come back, I’ll have to delete my comments and consider my time lost. Maybe I’m wrong in caring about that, and I got too invested in commenting what went a bit off-topic (but not that much).
Still, I find this pretty rude on the part of the deleter – although she did post a comment saying that she deleted her comment (actually, she deleted two).
The conversation is here, right below the original question: Should we use "in terms of"?
But I’m unhappy with the time wasted, and, most importantly, I disapprove of that user’s behaviour. What can I do? Would I be right to comment that such a deletion is rude?
