I'm a type of person who doesn't mind headcanons. The only issue I have with them is if they go straight to everyone's heads and it became "official" in everyone's minds.

Examples? MEIKO being a drunk biotch who smacks KAITO all the time. KAITO being stupid, pervy and likes to run naked. Gackpo being the perv of all pervs.

Or recently:  Neru = kanon for instance

The only way to prevent something like that is to emphasize that they're not official things. Though, there's no guarantee that it will prevent being a major fad in the fandom as some people who hear the headcanon may not emphasize that it's actually fanmade to someone else, it helps a little if not a lot. If that makes any sense.

All in all, it's okay to make headcanons, just be very careful with them as the fandom gets crazy with them and may do something that you didn't intend ><
