Yeah, they apparently noticed that I helped mathacks.com make skins that are undetected for all kinds of SourceMods. Took them only one year.

Will also never be applied to the CoD Series because hashing 6GB everytime you join a server is an overkill. They use the ZIP file format which caches the hash and uses it to verify the unpacking of a file. So they only walk through the filetable in the .iw files (ZIP-files) and can check it within a second.

nyyh ;(
