Yeah, I'll do a few things as soon as I get from work to make this work better.
EDIT: I optimized some code and now it doesn't lag THAT hard in the center anymore. Lol, it's a black hole of spam. We have over 18k messages right now and it keeps growing. It's nuts how much traffic already was wasted. We already spent 23 GB of our 100 GB quota, it's nuts.
Anyway, I also changed the start position to randomly pick one on the border of the rectangle (-5000,-5000,10000,10000) rather than (0,0). All hacker messages have been removed, but hacking is still possible. I'll fix that tomorrow.
