But this seems like somewhat of a new (and cheap) technique...
Yes, to cheap, but it has been around at least a few years, so it might be hard to say that it is "new."
They basically have your Link appear on hundreds or thousands of different forums...all they do is create a forum profile with a link on that member's member profile. (that links to your site)...
Well, google will basically see a spike of hundreds or thousands of backlinks to your site in a few days. Do you think that might possibly raise a red flag to google?
Also, probably a lot of those forum profiles are blocked by robots.txt, they have a meta noindex tag, or the links are nofollowed. so there value could be nullified.
And if it does work, and you leap frog your competitors in the search results, what's to stop them from spending $40 and leap frogging you back?
I should note that I don't know whether those links will work or not. When I look at my competitotrs at the top of the SERPs, they do all have those kinds of links. But do they rank at the top of the SERPs BECAUSE of the spammy links, or in spite of the spammy links, I don't know.
