Everyone has already mentioned that Your internal Rating is why you get paid out later or faster with your History.
Besides the "obvious" facts, like Your weekly/monthly transactions, the ATV (average transaction value), chargebacks, etc. There are still other "black-box" rating factors that influence your rating & therefore, the credibility you have. But it should be something to speed up quickly, do your business, avoid any disputes, etc.
The age of your Account plays a particular role. There is no evidence for Risk Management that you are more reputable just because you opened the Account a few years ago.
Regarding Blocking, it's the same with every Payment Processor and also with Adyen—if you are flagged once, it's hard to get rid of it.
They have a brilliant Risk Management (Adyen).
That is why you see, in most cases, nobody uses it in any Grey/black business.
