good morning Perky -
we put regular links on CL such as
http://Finca-Ponderosa.com and the hyperlink robot transforms them to this = " <a href="http://Finca-Ponderosa.com" rel="nofollow">http://Finca-Ponderosa.com</a> "
and it does NOT work to simply delete the "no" in their script
You are correct, this precludes the backlink for credits and also to traffic building which was probably their primary motive - why should Finca Ponderosa get the benefit of 35,000,000 monthly visits to Craigs List just because we put a link back to our site - understand better ?
