hackers never get perma banned
You have video evidence of this hacking
? And you sent said evidence to BW?
I have seen the Speed Hack
three times, but that was just before and after 1.4. Haven't seen it since. In fact, many of the sites with information on hacks state that many of the hacks were squashed sometime mid-1.4.
I have witnessed stealth caps on Voidstar, but that's not a hack. It's an exploit that BW can't seem to fix for some reason, and it's not really easy to accomplish anyway.
