I don't see how these guys are spammers or any of the other reasons that people categorize as spamming sites.
Does anyone know what spam is? Unless machines purporting to be from this domain are spamming them that is harsh to deliver that sort of judgment.
Sadly with the random categorization of sites as spammers that seems to happen on WOT eventually the program will become useless.
Please categorize with some value ad or don't bother, you will eventually destroy WOT's value
