Cloudflare could've just said so. Cloudflare also chose to make BYOIP expensive.

They could've explained the problem ("your gambling business is a problem for our IP reputation") and offered a solution ("we can switch you over to BYOIP so this won't be a problem"), but instead they sent in an army of sales reps that demanded an upfront payment for a product tier that they only needed one small part of, to the point of sales people pretending to be part of other teams.

It makes business sense to kick out casinos, but OP got fucked over by Cloudflare's shitty practices.
