Dave Couture — Forum spammer
Lately our forum and numerous others have been spammed with hidden links. The usual tactic is to post an insignificant reply in an existing thread, and to include a hidden link either in invisible text (matching our background color code), or hidden behind a smily.
This type of black hat SEO spamming is against Google's terms of service and is usually associated with throwaway domains that are not expected to have a long life, such as porn sites or online drug sellers.
The objective of this spamming parasite is to increase the value of his domains for re-sale. Black hat SEO spammers contribute absolutely nothing for the Internet community, instead they abuse other people's resources. Much like cockroaches.
