Even in the top-tier and including bonus payment, you can earn max of around $60/per week and that's for making 60 posts. The "standard" payment in other campaigns is ~$100/week for 20-30 posts, for hero/legendary ranks. The difference is huge and I don't think they'll be able to attract any quality posters.
Sure, you can still get good add exposure by paying peanuts, but that can backfire badly, as low payments + high amount of max paid posts encourage spam and nonsense posts. So there's a risk the community will lash out at advertisers and blame them for polluting the forum. And being a crypto-casino that operates on high trust, you really need a spotless reputation.
You are right on which making up some calculations which you would really be getting $60 for max 60 post per week as for users need to max it out on getting that maximum payment on which it would really be definitely be causing up that spam knowing that 60 post is really just that too much honestly but they did really stick into their standard or casual payrates and campaign rules and terms.For those quality posters then they wont really be that interested on joining on this one but for those posters who do really just agree with peanuts then this wont really be a problem as long they would be having a campaign.
The new manager that handling out this campaign is known on being that choosing about best posters but i doubt that the standard he would set might be lower as for the payrates arent really that high
or something that justifies on the amount post required. So quality would really be not as good to those good paying campaign but well it is on someones choice.
