1. It's sponsored most of the time, doesn't mean anything.
2. Fair point but all ICOs out there are building modern sites right now. In other words, they're investing in creating the perfect scam.
3. It doesn't mean anything, they could use websites to buy likes, subscribers etc.
4. Same as above, and a simple airdrop where people are forced to join the telegram will highly increase the number of participants. See how active the channel is, not how many are there.
5. Savedroid team are known and yet they scammed everyone. Scammers no longer care about being known to the public anymore. If they make millions, they could simply vanish.
6. Agreed, exchanges usually do their homework, better than everyone else.
7. I wouldn't count on it. Once again, Savedroid is an example.
My point is, If you want to find a good bounty, just take a couple of hours to search about the team members, read the whitepaper etc. If you feel good about it and you found that what they are promising is achievable and you believe thoey could deliver, go for it otherwise just don't.
I love your great analysis. The scammers have started even creating rating sites long before even launching their own ICO in under to game credence to perfect their evil.
