This looks like it will be a nightmare to check for the 50 posts, not including posts in this thread. Some could be short just for including the posts here, then what will happen? I await to see people paid out, and I wonder what results this campaign gave.
Almost everyone has
exactly enough, which goes to show how many of these are not normal accounts. We will be paying out as promised for everyone, however this type of marketing is saturated by empty accounts who only become active when it's time to post their bare minimum. Only a small handful of users actually look like real posters. The rest of them post 3 word sentences in random threads until they reach their 50 post count. We won't be coming back here for another campaign -- It was a tough lesson for us.
Payouts will happen within the next 48 hours.
It was probably a bad idea to pay everyone exactly the same as you did. It would have been a much better idea to pay members/full members less then seniors/hero/legendary accounts.
I also would have enforced a rule that would only count "constructive" posts which would weed out the "3 word sentence" posts.
If you are only going to pay for 50 posts then that is what you should expect to receive. Over longer periods you would likely receive higher quality posters (while you deny payment to the spammers).
It probably would have also been more efficient to employ someone to run your campaign (and put funds in escrow for payouts) to monitor for spam-like posts (like your 3 word sentence example) to handle signups and payouts. This would allow you to avoid the negative feedback associated with denying payments to people who are spamming to 50 posts, while still getting the positives of having cheaper/more efficient advertising then advertising via forum ads (which are very expensive)
