I was one of them. A lesson hard learnt.
Google cant warn of exit scams no, but it can show you things like who owns the domain, review of the site ect - I think that helps. One ad i saw for rollbit had 2 reviews both in russian saying it was a scam.
That is sad and unfortunate.
It must be emotionally painful to recall this scam, because you was one of its many victims. I give you some !PIZZA. Hopefully it will make your day somewhat better.
@madstacks! I sent you a slice of $PIZZA on behalf of @xplosive.

Thank you:) yeah it stings to think about it, But it has made me more aware of things now - It altered my risk taking dramatically , I am much more sceptical now.
