The troll's Accounts are banned, but we can still read his profile name and the topic he created stays in the forum.

It's not entirely impossible, some threads were removed when there was too much noise being made and it got Seph's attention. I'm not saying to make a ruckus every time, then again most of the threads that were removed were very drama filled and unlike the ones we see nowadays where it's just trolls

don't get me wrong I also think removing the threads is a better move, I just wonder how much power the mods have in order to do this
