This raises so many red flags, imo.
1: I have NEVER seen a casino offer a SUB that didn't have
WR. (At least in the past 5+ years)
2: 99.9999% of casinos will NOT let you deposit if you have an active bonus in your account. You must meet the
WR or bust out before depositing again.
3: Again, in recent times, I have NEVER seen a casino leave a sticky bonus in your account after cashing out.
In this case, 1+2+3 = 7.
Moral of the story: Something doesn't add up. With terms such as this (if the casino is on the up and up), they're just begging to get taken to the cleaners.
