The casinos that impose withdrawal reviews are usually pretty small nowadays and you won't find many of them as people tend to gravitate towards casinos with quicker transaction speeds. Most of them have gone out of business or aren't too popular.
What? That definitely not true, pretty much all fiat casino's have delays on payments and quite a few cryptocurrency casinos have them as well.
I mean just look at this thread, enough people have provided examples of casino's that make you wait days before receiving payments.
Not only that, they also randomly lock payments for review.
I'm talking about cryptocurrency casinos (I haven't used fiat casinos in quite some time, but most do conduct reviews as you mentioned); I have gambled on FortuneJack and several other casinos recently, and I don't get withdrawal reviews very often, but that may also be because I typically withdraw a relatively small amount compared to what I've seen other people withdraw, and I always conduct withdrawals from the same IP address and location. Haven't gotten a withdrawal review in FortuneJack in months because of this. I haven't ever experienced delays of several days either.
