You should have invested into paying someone on this forum, looking for a few extra BTC to monitor users belonging to your signature campaign.

This person could have issued warnings as the month progress, and inform you with a list of people, who do not adhere to constructive posting.

That way, it saves you time and money, and guarantee you value for your money.

There are loads of people on this forum, with skills to identify "Spammers" and "Cheaters" and who would have done that job for you, for a small reward.
