New selling tactic?

[troy]

Goodday my fellow webmasters,

I often go check a niche with some big link lists to see if the sponsor I want to promote is not getting overused.
I don't know if this is new but what I see very often lately is one or two domains posting the shit out of one sponsor.
I mean out of 20 new 12 are of that domain and of that sponsor.
Is this a new way of promoting?

are you sure they are not free hosted sponsor sites? Or maybe a paid lister or the webmasters own sites.
