I have some useless domains that I'm just letting expire... at least a couple of them were blacklisted by Google due to some pretty stupid stuff awhile back... lol
Add domain to blog networks like ALN and enjoy free submissions
how can you tell if a domain has been blacklisted?
I'm leaning towards installing wordpress on 6 of the domains and using them as buffer sites for my own mini link pushing setup (2x4), if they get black listed then it's no big deal since i don't intend on re-newing them
Might outsource the content for the other 3 and see how they go.
In the case of these domains, it was pretty obvious... they were rising through google using keyword stuffing techniques and then completely disappeared. lol
