Honestly I don't believe that the main target for his advertising is Bitcoin Talk users, yes he may get some new users from here. To me it seems more of an effort to advertise and move the page rank up in Google and Bing. The amount of backlinks on other sites helps to raise your page rank. Advertising this way, helps keep cost down if you were to use Google Ads or something similar.

Im happy with Seal's service. He is always on point and doesn't change what he expects from us.
