This has come up before. The main issue is that ponzis are very similar to both other gambling sites and real investment sites, so it's difficult to create a category that includes exactly the right things. How about this:
Investor-based games
Games where the main factor is whether or not new "investors" join the game. Also any Bitcoin-denominated investment product with an APR of 15% or more, which are similarly risky even if they're not actually paying interest using investor deposits.
Would this description cover any real investments or non-ponzi gambling sites? Would it fail to cover any ponzis that have existed in the Bitcoin ecosystem?
Also, are any actual users of the Gambling section irritated by this, or are people just trying to hide this kind of game? Is anyone
against the creation of this section?
Most definitely there are people against the whole idea of a ponzi. SOME ponzi's have the ability to store 10's, 100's or 1000's of BTC like cryptodouble did and rob users in the end. The community needs to figure out trust system if you want to make this section work or else no one will know what is legitimate or what is not.
See my thread:
https://bitcointalk.org/index.php?topic=923461.msg10135856#msg10135856I hope that you do make this section, but at the same time organise how you will flag the scams and how you will flag legitimate sites. Just like this forum, if everyone has a negative trust rating here no one will know who is a scammer and who is not. That is EXACTLY the situation this section will go through if all of these biased and default ratings continue.
