If you abused a system or breached a contract or do anything detrimental to any service or platform on any sector, I believe every company and platform shares this kind of "information" amongst each other. But it's not like they're crazy enough to share essential things of their well-behaved customers. After all, it's on every company's interest to keep their best customer a secret from the competitor. Lest the competitor grabbed that customer from their hand.

The simplest and easiest instance of this practice, just to give you a better grasp of the idea, is credit score. If you didn't know about it yet, I'll let you in to one of the big secret of financial institutes: banks share info amongst each other of bad creditor. If someone applied a loan or credit card and they got defaulted or always paid late, the issuing bank will warn other banks that the user should be treated with ounces of caution. If that customer always pay on time and has a good credit score? I don't think banking corporation would share that data, as they have no reason for it.

Simply put, if you adhere to the rules of any entities, there's no reason for them to share this info amongst each other. It's a completely different story if you're someone who did something bad against that platform.
