Some people just wont learn ...
These cards are being blocked left and right by Polish banks.
It doesn't matter if they are sold by seller A or B
What matters is that some people that buy them will use them to either commit fraud or siphon stolen funds and then the bank will block the entire batch of cards.
Buy them and put your fund there at your own risk ...
mBank has done that one time or twice, I mean chain blocking, that's why I've never been selling those.
My cards are from BZWBK, I've also never heard of anyone experiencing group blocking.
