Black hat SEO is not worth time and effort anymore and it is far better to channel your efforts into white SEO techniques instead. Techniques for black hat are heavily scrutinized and the penalties are quiet harsh that what little benefit to be gained is not worth it. The benefits derived from white techniques, such as higher organic traffic and better customer reception far outweigh any 'advantages' from black hat.
Attention: "role based name" email prefixes such as support, webmaster, info, contact, forum, service, affiliate, admin, traffic, partners, marketing, etc., for our member accounts are not permitted. They are acceptable for a vendor listing, but not for the member email. This is due to bulk email processors scrubbing them for delivery due to extremely high bounce rates. Please apply for membership using a personalized email prefix. Something like email@example.com.
If we discover you signed up with a role based name we will give you only one message to change it. After 3 days your account will be removed if the email is not changed.
