Most of the bloggers are busy removing and deleting links away from their blogs. My blog buddy had also removed all the links for all the paid posts networks and so far everything is fine. I dare not do so for companies like SR, RM or Payu. I am not sure if those companies require permanent links, so I didn’t remove mine. As far as I know, Payperpost requires the posts to be up for 30 days, Loudlaunch for 45 days and Blogitive for one year.

Anyway, it will be a lot of work if you wants to remove all the links, unless you label them accordingly or trace from the networks. But if it helps in protecting the PR, as it’s shown on some blogs which remove the links on regular basis, then it would be practical to do so. However, some advertisers might not like it. So the decision falls on individual bloggers.
