I think most casino players do not use blacklisted strategies because these tactics can get them banned or blacklisted from the casino. Casinos are aware of advanced strategies like card counting and have measures in place to detect and prevent them. Players who are caught using blacklisted strategies may be asked to leave the casino or have their winnings withheld. Therefore, most players tend to stick with basic strategy or other legitimate betting systems that won't get them in trouble with the casino.
