No shit Sherlock, LOL. Most these folks don't copy right their stuff also. This is a Pirate Site, period.
But this is a Pirate site, you raging nubsack! Man you delusional mind needs to get it's shit together. Some of the creators arn't aware their stuff is here, also there are so many clones like sites of this site, they just throw their hands up and hope all that pirating gives them some money towards their accounts.
Some actively release public releases here(Or try to, but folks will pirate stuff over one pay grade scale releases).
But at the end of the day, this is a Pirate site(Among many, so so many)
