The big G doesn't allow anyone to sell backlinks, and the only exception of that is if you include the no follow tag. So basically I'm asking if it's dangerous to promote your money sites\buffer sites on these networks, like Linkvana or SEOvine? They said they would deindex sites that have are involved in such activities, and I wouldn't want my money sites deindexed, not even my buffer sites since they're valuable too. I know that these networks do work at the moment, but is it a safe bet to place in terms of the future? I mean, anyone from the G Spam team can just sign up to these networks, make a few posts, track them down and deindex that site and all the sites that are linked to that site. This may sound crazy to some of you, but if you think realistically, why wouldn't they do this? These type of activities are totally against their rules. Please post your opinions here so we can have a great discussion. Thanks.
