actually after trying this visitor boost, it turns out to be a total scam. Apparently they are sending bots to the website randomly clicking any link appearing on the home page. "when i see active users online, i see guests only viewing threads can be clicked from the main page". Don't know still how are they getting all these different ip addresses, but for sure they are not helping any online starting business.
Registrations came from 2400 unique visitors, as they stated, are NULL. All my new registrations came from invitations emails and the tell a friend link. Another thing, compared to my forums activities in the previous months and till now daily improving activities i think they only got me around 1500, and reporting mistakenly 2400 uniques till now.
Anyway, that's what you get i think for cheap advertisements and believing scammers.
Just though you ppl would like to know.
