Why are "Go Free Date" (gofreedate.com)
"1 Doctor Love" (1doctorlove.com)
"Bride Heart" (brideheart.com)
"All Single Ads" (allsingleads.com)
on my Grey List?

These sites are all part of the same kind of place. They might or might not be the same place, or related, but they have the same style. Scamming.

The profiles are all pretty much fake.

If they are not fake, they are copied from other sites.

There are no sites worse than these ones. It is all fake!!!!!

"Birds of a feather flock together"

These sites appear to be the same site or affiliates...
