How do you dictate whether an ICO is a scam or not? Do you provide market depth research or information, or is this purely based on feedback left by others? What actions or features do you have in place to help eliminate spam attacks by fudders who create bot accounts on your site? While this is a great idea, in theory, you have to be cautious about offering any form of "financial advice", especially when dictating what you believe to be a scam coin or not.

Good luck
No,it`s not a great idea,because everybody can create a Facebook group or a Reddit subreddit for free around that niche.Having a forum requires paying for hosting and advertising.Identifying ICO scams can help a lot,but we have to make the difference between real ICO exit scams and failed ICOs that didn`t manage to complete their project due to lack of funds or other issues.
Good luck with the idea,OP.
