Where do I report hackers?

I have 2 hackers to report. I posted them in the "MyMNCServer" thread but I'm not sure if that will get the job done or if it's even the right spot to post.

Here are the 2 videos of 2 seperate cheaters.

If anyone knows where I can post these videos for proof let me know. I'm really at a point where I can't take any more crap. :evil:

Erm, you already posted in the correct thread. :shock:

Oops. Sorry I thought I may of misread or something. :roll:

*Second Video*

"Lol, remember the Hentai tentacle guy we ran into?? BOOM BOOM BOOM TRIPLE HEAD SHOT"

HAHAHAHAHAHAA.

:roll:

Not to discredit this or anything but I'm pretty sure you aren't invisible when you are running around like that.

I already added him to the thread over on the steam forums. But the video proof helps too. I will add that.

BTW, what skin are you using for steam?

It's called Apparition, pretty sweet skin. And thanks.

We ran into him before I knew he was legit xD
