[General Superhero] How isn't unmasking and identifying all superheroes with a hidden identity the #1 priority of all super villains and bad guys everywhere? Wouldn't that help them more than landing some punch ever could?

Do you want Identity Crisis?  Because that's how you get Identity Crisis.

The reason some villains avoid it is because it turns the entire hero/villain game very *personal* and dangerous.  Flash probably represents the best version of this.  Flash's villains consist of a guy with a cold gun, a guy with mirror tricks, a guy with boomerangs, a guy with gag gimmicks, etc.  If he wanted to outright murder every single one of them and reduce them to subatomic red paint smears, he could do it.  Why not?  Well, it turns out some of the older rogues actually do know who he is and who his relatives are.  There's a literal agreement between the two sides to put a cap on how far they're willing to go to get away with/stop crimes.  Flash can even sometimes call on his rogues to help if Keystone or Central is at risk from bigger threats.

Identity Crisis and several of its follow-ups is a story about what happens when the villains suddenly discover that the heroes have been breaking those rules for a while.
