Being banned from a casino for card counting typically means you're not allowed to return to that specific casino, and your details may be shared with other casinos, potentially leading to broader bans. Although card counting is legal, casinos can refuse service, and repeated offenses may result in increased surveillance or even police involvement if cheating is suspected. A ban can also harm your reputation, making it more difficult to play at other venues. For some, the ban may affect their ability to enjoy or profit from blackjack, but many counters adjust by finding new casinos or refining their techniques to avoid detection.
