Mad Hax0rz bro.
I just got my rear handed to me by a 5-stack, two of which we have confirmed to be hacking. One of them told us (dumbass) that he was running BoL, which none of my team had ever heard of. Google provided me with This site, and... Wow. No wonder we lost.
The other was running a ping script, according to one of my other teammates. He knows what he's doing with computers and recorded hundreds upon hundreds of pings on his system, causing the enemy thresh to spontaneously achieve superspeed.
Anyone else seeing this? This is absurd.
