when investors and the crypto community already believed, but the team said differently!
- The team did not respond well to the crypto community.
- The team is very shady and does not provide updates about their projects on the telegram & social media channels.
- The team plans to take a vacation
- The team blocked accounts one by one from each community who questioned about the development of the project.
- and finally
you are banned in this group 
it's so annoying, how you feel?

I think I know some of the criteria you mean. first it is better to go away from them because based on what they are doing it is being scammed and they have no plans for new development, while many tokens and coins are developing new features to stay afloat in this industry.
This is a good lesson before investing in projects like this, where you have to understand whether the team is working seriously or just want to rob your money.
Fraudulent projects operate differently and it always hard to notice them right from the get go. Besides, understanding the project team serious working level didnt justify any project to be scam free and i think the best thing to do such situations is to be relevant with the project news in other to easily spot out some unfair thing done by the project team.
