I like the protectcopyblogs plugin however in the code it ASKS for ONE credit link... then takes FIVE do-follow links per page and post!
Excuse me, but I think that is ABUSIVE. I've left the links in as ext,nofollow but if I had a little more nerve I'd wipe them entirely.
Yes, plugin writers deserve great credit for what they do, but a single link is more than enough, and preferably not a bunch of keyword-optmized do-follow links.
kvetch! kvetch! kvetch!
And yes, I do know there are alternatives... I'm just giving the guy a chance to rectify his unethical coding.
