JazZ/Yola was on this server for a while before this spam took place, and he was making it an obligation to troll/fame a few other people present. I don't have screenshots of those moments, sorry, but he left and returned 5 minutes later with this spam.
Here's are a couple of his ID's I've found (he mentioned he has had over 20 alts, so there are probably other's I am not aware of):
JazZ 44611 2015-12-18 14:39:34
JazZi 45254 2014-03-27 03:00:00
If you found the name familiar, JazZ/Yola is the genius behind
this drama Badspot did. As Badspot himself is saying in this thread, he's a known problem user and you might want to ban him or take note of his presence on the game.
