I wont file a spam report - ive read too often that g does nothing anyway mostly.
They do even less when you don't file a spam report.
Results don't happen over night, but they will eventually happen in my experience.
Just don't expect to see them whacked in a week or even two, but it they're being bad and you explain to Google how the ownership ties all those site together properly, when the report gets into the right hands it'll be dealt with.
Unless you're doing it too and don't want them looking your way, which is a good reason not to report.
