I'd like to ask you a question, what is the point of your large "warning" list, you could'nt have possibly tested all those sites, so you are just assuming based on very superficial data that they are in fact out to scam people. I understand the likelihood that a certain site, promising high returns, will turn out to be a scam - but then what's the point of maintaining a list, it's not like you have a list of trusted sites of this kind (let's call it: hype) because there aren't any. In fact I would bet a lot that you spend no more than 30 seconds evaluating a website to see if it checks your boxes and then it lands on your list, which is both unfair to the site owner as well as disingenuous as you're not actually doing any kind of honest investigation, I don't see you posting payment proofs (or lack there of), or anything else. Why not just say - if it's an investment site of any kind (that accepts bitcoin and promises high return), and is not a gamble site, is (according to you) a scam, and just leave it at that.
Opmac already answered you with short and easy to understand words.
" All ponzi = quack quack quack!!! " 
But the part that talks that took 30 seconds to judge a website? you're wrong!
In my opinion I do not take more than 30 seconds to judge the site as a scam, I take
1 second to say that the site is a scam, I do not post website that are scam according to my opinion, post scam sites second opinion:
HYIP Monitor sites,
idiots investors,
renowned blogs and
Review sites. this takes time...
