I don't think prizes are a good thing. It would just create bad feeling if one didn't win one. 
You've rejected account sales, but I hope you will reconsider this. Account sales mean that the reputation rankings are meaningless - I ignore them, and form my own opinions from current posting activity. Also, it is another thing contributing to bulk posting of low value comments.
Blocking signatures completely would be a bad thing in my opinion. I use my sig for various minor things, such as selling bitcoin domain names. This is the only option in this forum if one wants to offer Bitcoin domain names. The market place is full of not very interesting ( to me ) things, and threads are constantly being bumped. However, the problem with signatures seems to come from supporting signature campaigns that posters don't use themselves. They just see them as a means of gaining revenue, and don't care if they are honest, or if it damages their reputation by promoting the sites. One solution could be to restrict links to domains that are owned by the poster. I believe that this would cut out many of the posts that are made to scratch a few Satoshi.
An open board for discussion where a (full) member requirement for posting would be a good idea in my opinion. This could provide very useful reading for guests and junior members, and could generate some great discussions. Advertising on this board could be more valuable for the forum owners as well.
On a personal note, I would like to see a dedicated board for the sale of crypto related domain names. A paid sub-board with registrar advertising, where the registrar accepts Bitcoin or other cryptos, could provide another source of revenue for the forum.
