I subscribe to both the Dave Naylor and Andrew Girdwood blog feeds.
Dave Naylor has just posted about links from the bigmouthmedia homepage being, in his opinion, spammy because they are hidden. Andrew Girdwood is (I believe), head of search at bigmouthmedia and a strong advocate of using no-follow, avoiding spammy techniques and paid links.
It’ll be interesting to see how Andrew replies to Daves’ post.

JC,
Recently purchased http://www.googleslaves.com for 14 pound, recently tried to sell but no offers.
Similiar to affiliate marketing I suspect – a little black art, a little logic & some luck required.
