Imo, there are some pretty decent competitors of mpgh, but the worst has got to be gordons. They have about 1 active mod. 99% of the hacks openly show screens where they are leeched from gmhbst (can't type name here due to censor but you know it) or mpgh, and the users don't even care.
They even credit themselves when it says "zodiak mpgh pub hook"
What can you do about these? Nothing really. A lot of hack forums are run like shit with low to zero organisation at all. You can post on their thread and expose them, but the users are so stupid they wont even notice, and keep thanking the leecher for "making" a hack.
The reason why many forums have crappy organisation is because the administration is exclusively about 12-14 years old and they don't know how to maintain a site.
