80% scams in which way, as in like leaving with all the money right away (like a planned scam) or did they just not manage to deliver?
My guess they are talking about planned scams and technically failed ICOs that never refunded their investors.
that sounds logical, well, technically failed ICOs - should/could the money really be redunded? in a sense it was collected to fund a project, if it then fails, it's not really fair to get the oney back as the money was supposedly used in the first place?
