Clocking is a black seo technique, in which black hater uses two url one is for search engine and other is for users. With this technique search engine get diverted.
some affiliates get very angry when you cloak, others dont care, some even suggest it. Many advertisers dont like junk traffic so people use cloaking to obfuscate the origin of the traffic. it can be considered blackhat but it is more greyhat, against SOME peoples terms of service but not everyones.
