What do you think about a platform where you can put the address you wish to invest on and it detect if it is a ponzi scheme fraud or not .?
It works theoretically but it's simply not practical.
It's like those pages with a list of known scams. While it may be useful, when a site is reported as a scam most likely the admin will have already exited and stopped promoting, meaning that the list of scams can often be redundant when it comes to actually protecting consumers. The currency and relevance of such a list is debatable imo.
Likewise, with your proposed service, I think not only will it be difficult to try to even try to get a portion of the addresses associated with known schemes, new ones are popping up every day that you'd have to document. It's simply unfeasible to update that often. Much better to teach people how to spot them instead.
