Good, but still not enough. Those are just a small selection of users on this campaign and he only seems to remove people once people alert him to them. He himself needs to go through the spreadsheet and kick all the shitposters off and not just rely on others to run this campaign for him.
Considering the fact that he is losing his own money to lot of shitposters, I wouldn't say he is doing so because he is lazy or anything, going through 1000s of posts in local even if its translated, is a lot of work. Either he should hire someone to manage the campaign for him or remove Local and Games and Rounds from eligible posts
He is still getting very cheap advertising to have his ad plastered everywhere and it doesn't really matter where the spam is as it's still an ad impression for him regardless of the content of the post. I have suggested that he removes Games and Rounds and the Local boards as well (no idea why he pays for those when most of the other boards are disallowed and those two are obviously the boards that can be easily abused). I would say it's laziness that he does nothing to curb the spam and possibly even being cheap that he wont hire anyone to get on top of it if he can't.
