I dont know the sites, but I can give some advice for How to avoid ICO scams:
- read its WP (whitepaper)
It is important you read the whitepaper of that cryptocurrency you intend investing in. What to except when reading a Whitepaper:
- An identified problem. To what purpose will the currency be.
- Do the project have a solution to this problem identified? You need to understand the technology behind the solution provided.
- Distributed/ Implementation of Tokens: You have a product in view, how do the tokens come in? What role are they to play? Why do I need a token to use the product? How will I get the tokens? A pre-sale, bounty programs or at an ICO sales? What percentage will be given to the public? For how much will each token be sold for at the pre-sale and at the ICO sales? What is the detailed plan for the project? How long will it take them to launch the coin on a platform exchange?
- Who are the team members?
The team members will consist of the CEO, developers, Advisors, Blockchain Engineer. Who are they? Do they even exist? Do they know what they are talking about?
Finally, what is the main emotion you feel?
After researching, when you get answers on these questions, you will know what to do.
Remember, ICOs can also be scams. Trust only yourself.
