I do agree on services sharing banned users data, for safety or compliance reasons. But this should be limited to a set period of time, because the person you were 10 years ago grew up from who you are now and will be in 10, 20, 30 years from now. We all grow and hopefully learn from mistakes.

An implication of this “banned users” data sharing is that this data exchange must be overseen by regulators, to enforce equal access to competitors to this data and also that companies drop people from the “banned users” database after some time, not penalized for life except in rare cases.

I would argue that most users’ petty behaviors that lead to banning do not deserve to make them pay for it the rest of their lives - and that there are rare exceptions who do deserve to be banned for life because certain users’ behavior is so egregious.

Also, consider cases for jurisdictional banning and global banning. Some behaviors are not allowed in certain countries. Take a gay couple kissing in a car in Saudi Arabia - should this couple be banned? If so, just if attempting to use services in Saudi Arabia, or globally? These are serious and important considerations.
