One way to scare new users away from the platform who don't know how to use it properly is to flag them for unintentional infractions. If they are delibrately spamming the tag with things that break community guidelines, then sure. But still being a new user myself, I'd rather be corrected in a comment or a dm of some kind than having my posts attacked by a swarm of do-gooders.

The other thing that would be helpful is if more of the veterans of this platform made sure to permanently include information on how to properly participate on here somewhere in their posts. The minnows look to the older members for guidance, and your posts are what I look for when I need info on how to improve how I participate. The last thing any newbie wants is to feel ostracized right off the bat. That's gonna keep Steemit small forever, unless that's your goal, which I don't think it is.

Just some thoughts from a new guy who is probably still using the "wrong" tag now and again.

Also, who defines what is the right and wrong usage of a tag? Tags might start off with an innate definition, but they certainly take on a life of their own. Tags mean different things to different people because words and ideas mean different things to different people, especially across cultures and languages.
