Yup. Not Copyright, but "moral rights".
People making money with freely available hacks.. How disgusting.
Do NOT use these websites, they makes money using link shorteners everytimes.
Plus, its EASY AS HELL to add some "password stealing code" into a hacked client.
I have a POC, but i will NOT RELEASE IT, obviously.
Unless you trust thoses websites or want to decompile the client and check by yourself if the clients are clean, i suggests you forget them.
Maybe you can report them to the hoster?
PS: No problem with hackers who sells their own stuff. Problems with those website you mentioned.
