I hardly advise against this kind of gambling. You have bigger chances at the casino. In casiono its like 49:51 (win loss) here it is 1:9999 and reward is not worth the risk.
Yes it is not possible to detect all of that one by one. seems like right know its not about people looking for a good project. but a project that must be able to reach potential customers. with big promotions can be a plus point. but this can also hinder for good projects without big capital to exist in market.
In my opinion, it is better to look for platforms with working product or app that are actually serving existing users. The team can publish all their credentials but in the end, most of them can't implement the mission they want for the project. If the app has useful application in the day to day life of a regular user, that may have the chance to survive rather than application for selected customers.
