Welcome to WebmasterWorld Guest from 220.127.116.11
just regular sites, articles and blogs linking in the regular way they always have
The worry is that websites can be penalized for linking to a bad neighborhood
If there weren't so many unethical "web publishers", the rest of us would be at the very minimum, 200% better off.
I'm not saying I like this - not one bit. But I do understand it.
I emailed a dozen of them and only two responded. Both said they were aware that PR is still lost through the nofollow link. Both said "better safe than sorry" somewhere in the email.
A nofollow means no PageRank is transferred.
Now if by "credit" you don't mean Page Rank in the strict sense of the term, then that is something else and very much open to speculation.
Were these naturally occurring links to begin with? Or, were they solicited?
If natural links are no longer registered by Google because natural linkers tend to be cautious and use the threatening nofollow attribute
