Who will be the last one to comment?

The system uses mods, but very old comments may be duplicated and not changed. The oldest I had was a question that I asked was simmilar to one that way 7 months old, I believe. I think it just depends on the mods memory, or if they think the question should be revisited, if it could contribute to the site or it was interesting.

Besides, mods can check through questions you’ve asked

Anyone can see the questions you ask.

And your answers too if you have that enabled.

It depends on whether someone looks up the older thread and references it in the new thread.

@XOIIO @marinelife: I see. It is manual and mod-memory-based.

@johnpowell: of course they can look through everyone’s history but no one would bother to do so. I never see a question posted and then look through the history of other posters to find a match.

@malevolentbutticklish :: I was responding to @XOIIO assertion that it was a special mod power. It isn’t, anyone can see what you asked. I should have have clarified that.
