I used to be friends with this guy, he was a regular on the MG server. He has had many Steam accounts, you know why? Because he's a cheater himself and his bhops when we played were unreal, we all suspected him, but his bans just confirmed it. I wouldn't trust this plugin on our servers.
This was in pG. Also paging
HirizaKyo.
EDIT:
Now I remember. He actually also or used to sell an auto-strafe optimizer bhop script and we ended up getting him banned IIRC. I'll see if I can find his shop.
Yup, I found it. Looks like he got his own dedicated site these days, I wont be linking it. Leadership can PM me for further information about his website/shop, or try to google it themself.
Here's his alliedmodders thread for Cow's Anti-Cheat:
