Perhaps, time to blame managers for situation like this one. What's the point of employing a non- gambling poster for a gambling signature campaign.
It's not the first time I have done this. I accept non gambling quality users and monitor them. If after a certain time, I'm not satisfied, there have been few cases where I sent them DM to not post in gambling section or at least made it as their wish. It's better to get a quality non gambling user than a genuine gambling board spammer. Maybe it's just me who thinks this way.
