We all are well aware of ICO
frauds.
I use the strategy to start with a whitepaper, see team member details and the roadmap.
What strategy you adopt to make sure the ICO is not a scam/fraud?
The code, whitepaper, the history of tema and the community feed back about that. But it will be very important to understand the code. Remember the community is also playing a really important role to determine which is a scam ico. Because you will have more support data.
