I wonder why they're so dumb to use photos from free stock images websites and then think nobody will notice it. There is no need to make a reverse image to check.
And if they think they will be fine with removing the photos once exposed (which they usually do) then there is always the google cache to use (considering the site is indexed of course)
The next generation will use
The Care Bears photos to represent the team
Investors are dumber. If not called out by people like OP, they would never bother to do their own research. Even though this ICO will be flagged as a scam and a feedback would be left, there are still chances they would make money out of it. That's how their business works. Their victims are not the 60% of smart asses but the remaining 40% who get introduced to cryptocurrencies every-day with a hope to get rich. The only possible solution to put a stop on this is awareness.
