Thanks for the fast response
As far as I'm aware, they are standard freesites, all of them hosted on thumbler.com and submitted by thumbler (which is obviously me LOL)
Most of them are listed by people like Jay, GG, Hoes, Penisbot, HQ etc so I would have thought they should be acceptable to you, although obviously it's your linklist and you can list or decline who you want!
Just seems odd that none of them are there.
