It may be that they're after a specific industry(ies). Just this morning I got two emails in regards of one specific ad group for some payday loan company that I'm an affiliate of.
This means that they can suspend as many accounts as there are such ads within them, regardless of the fact that an affiliate does not have a control over a site in order to implement changes.
On the other side it is true that an affiliate has a control over companies he/she wants to work with.
