Seeing as OP was a part of a pay per post campaign co-managed by me back in their junior days, I'd have one more question, if I may:
If someone is in a pay per post campaign then he will try to post the maximum number of posts counted in that payment period,hence creating spam.
If someone, let's asume it's you, was in a pay per post campaign, then you were trying to post the maximum number of posts counted in the payment period, hence you were creating spam.
Right OP? Were you sig spamming?
