Forum:Lv. 70 Mordechai?! What is this?

What is going on here? I just started playing co-op recently, although have all characters at Lv.50 and a few 2.5 playthroughs with hundreds of rare weapons. Some guy pops in as Mordechai and is listed as Level 70 with ridiculous weapons...crazy, ridiculous destroy all in one burst of explosive nastiness stuff - just a total KNOB as well, shooting all co-op characters repeatedly and stuff like this. I was completely unaware that you could mod weapons on PS3, and what is with the level cap of 70? Anyone else see this sort of thing? Really, if I could make a suggestion to Naruto, the level 70 dude, why don't you just go play with yourself - pun intended - or learn to play nicely with the other kids. Cheers.
