I want to ask if how can I use pub cc on any cardable sites

if u can find one that will do it sure  but normally  not  gonna happen u need  private ones  even then u need to know  whats up with the site as well

i dont quite get what you have said. can you explain it to me further?

most of public one will be dead thanks to people that dont card

it depends on the cardable site , but you need private
