Back on Reddit there were people who set up scripts to automatically delete comments after a set amount of time to prevent people from looking at their history. As you could probably guess, they were usually the most stubborn and argumentative sort on the platform.

Though I've upvoted that user before and I normally don't do that to people being disruptive, so who knows? If only there were some sort of history that would tell me what kind of user they were...

We sing. We dance. We are a simple people, sahib.

Can you see when a user has deleted comments?
