They are. I get tons of PMs a day and I'm also talking to users. So far not even a handful of users requested that.
The 400 post ones only get cheated most of the time anyway by the way.. Try to make 100 decent posts a month without rambling one-liners for a change. I certainly could not do that without making up text that is not really "me". (and also sound like trying too hard while doing it)
A hundred are 3.33 proper posts a day. You don't have to post every day, you can do them while still having a life and not being online 24/7. This is more honest to me than any other way that focus solely on quantity.
This is a marketing campaign, it's about real users making quality posts and just being themselves.
Payout is guaranteed, so everything is fine for those that do not try to cheat the system.
I did not get the bold part. Care to explain ?
