That wasn't a case of fraud, it was a case where they didn't stipulate the maximum profit properly.
This is understandable and since then Roobet hasn't caused any further issues as far as I know (please don't underestimate I don't read posts in the forum!)

A genuine mistake is not the same as withholding your funds for some clause from the ToS that sounds unscrupulous.

Sorry but you really can't compare between the two.
