I'm not sure what you mean. Are you talking about us (mturkcrowd)? You certainly don't have to pay us money to participate. The board does accept donations, and many members have done that. But many others have not.
The purpose of this board is to come together and pool our talents. We share information and (hopefully!) impart a bit of wisdom that we have gained over the years, working on mturk.
Hi, are you trying to post a link to something? Our spam filter blocks people from posting links until they've made at least 3 posts (Including replying to a post with a link in it.) You're at 4 now, so you should be fine.
We don't require payment for anything HIT-related. We do offer a couple extra forum features to forum donors, but those are just minor quality of life features and certainly not required to find HITs here. Non-donors can see everything that's posted that donors can.
