This begs the question - what exactly did you pay for? What are the "services" that cost you $8k with a "limited offer"?
If I had to guess, I'd say it was the usual money grab most of those ICO rating sites did. "Pay me an insane amount of money and I'll list your (scam) ICO with a review saying it's decent". That's how most of such sites I saw (and got the chance to talk to either the operators or those listing / trying to list there) operated.
But this only proves that rating sites are not to be trusted at all. A good evidence to refer on.
Sure, but at the end of the day, they're more or less a byproduct of ICOs themselves which "collect" / scam huge amounts of money from "investors" and of course, other "services" emerge which also want a piece of the pie. Might be annoying for those 2-3 ICOs which maybe had honest motives, but that's probably just collateral damage.
Never, ever give money to anyone without securities. Ever. Even less so in Cryptoland.
