So the question here is pass on the offer or would everyone rather see a manager attached to the campaign?
It's a double-edged sword: we're better off without the spam, but helping them hire higher quality posters helps them to get better quality advertising and reduce the (already very slim) risk of their campaign getting banned by theymos.
Since you're posting my quote: I've seen several users tagged for promoting a scam in their signature. I've only done that once (
here; feel free to add more) and won't do it for campaign participants, but all it takes nowadays is one out of many DTs to ruin somene's reputation.
I doubt a campaign of this size is even manageable. Pajeets are coming.....
The first step would be to set a Merit requirement: if someone haven't earned at least 10 Merit in over a year, he has no business in any campaign. If someone bought 10 Merit for a bad post, that easily disqualifies him too. YoBit could for instance use
my list of earned Merit to reject anyone who doesn't meet a certain minimum.
