I’m not sure how long it has been in place, but know it definitely has not been enforced with any regularity but FD seems to be enforcing their rule of only paying out winnings. I recently made a deposit, won and lost some money and then wanted to make a withdrawal so I could play more on DK but my withdrawal on FD was declined because it was for more than I had won. After a lengthy back and forth with customer service I was informed that even though they have not been enforcing it with any regularity (by their own admission), they would only allow me to withdraw the amount I had won in contests. Meaning, if I deposit $50 lose $20, but win $3.60 of it back, I could only withdraw the $3.60.
Let me be clear, I don’t have an issue with this by any means and understand that it is in place because people like myself hop from site to site with extreme regularity. I just wanted to point out that for a small time player you should be aware of this because the last thing I wanted to happen was for me to try out FD and their new MLB scoring (with late swap) and dislike it but then have my money stuck there until I can win enough of it back and I don’t want that to happen to anyone else.
Again, not complaining (other than wanting sites to be consistent with their enforcement of rules), just pointing out my experience and that FD (and maybe other sites as well) seems to be cracking down on this.
