I want to obscenely insult a redditor
Any good reason for doing that?
Yes, he once slandered me online
Well I think it might be worth letting it go. Playing into a trolls hand only feeds him to do it again.
That's fine. I'm going to pull a prank on him when I see him offline.
Pranking him might also make things worse. If people didn't see what he did online you might look like the bad guy if something bad happens with the prank.
