Hello guys,
What is the best way to protect against main.exe crack ?

Why are they cracking? Whats the reason?

Packing with good program and Checksum server sided..? Or anticheat with server sided protection..

I speak some main decoder that can prevent cracks, or if this is a ' mission impossible ' ^^ or even a anticheat as @karipidis said, but that prevents it well ...

Because with my tests I always StudPE use to hook the dlls of my antihackers and MoleBox for compression and ' crypt ' ... But I believe that this is not a very safe way to hide certain types of cracks ^^
