Stuff featuring my samurott character, Sammy, who does not have a tag, and my Leavanny character, Melanie, who also does not have a tag, have been erroneously tagged as cyan_(skybluefox) and erin_(skybluefox), presumably because of this image:

While the samurott depicted here is indeed SBF1's Cyan, and also does feature Erin, Erin is not the Leavanny. She's the mienshao in the back. Regardless, some well-meaning but wrong tagger must have thought that erin was the leavanny, and thus retroactively tagged all hambor12-tagged posts featuring a Samurott and a leavanny as being of Cyan and Erin, despite the previous picture being the only one actually featuring Cyan.

example:

https://e621.net/post/show/1681338/-3-anthro-balls-bottomless-breasts-clothed-clothin

Again, the character of Erin is not a Leavanny, and the Leavanny tagged as her is a different character who does not have an existing tag.

As the artist and creator of the characters, how would I go about this? Do i just delete the tags with a note informing that the characters tagged are not in the picture itself? And how would I get a new tag for the OCs in order to prevent the above "kind tagger" in case they get confused again?

The characters featured and erroneously tagged as cyan and erin are these OCs

Sammy (tagged as cyan_(skybluefox))

Melanie (tagged as erin_(skybluefox))

First and foremost two major things here: names are always tagged with external information, so as long as you can point out source where characters are stated, those are fine to be changed even if they look a lot like other character or even just something like regular unmodified pokemon.

Secondly all users do have the ability to change tags on any post posted here, so if you do see posts with erronous tags, simply fix them. Do this by pressing Edit either under the post or on the left side panel. Creating tags is also simple, you just insert tag that has never been used in the tags and now it's a tag with 1 posts in it.

Character tagging in some instances is extremely hard, because sometimes artists write descriptions like "Characters owned by their respective owners." and looking at owners post there's description of "Featuring my character." at which point it's nearly impossible to correctly tag the characters when it's assumed that everyone just knows them. Examples given are good, first post would require user to have Furaffinity account to see the description and second post the sources do not state characters names, so looking at tag history both posts were tagged character by same user based on visual information of that first post you mentioned, so the user most likely wanted to be helpful and give credit to character owners but didn't realize the names were wrong.

Characters are tagged similarly to any regular tag, simply tag the posts with Sammy_Masamune and Melanie_Vanneleigh and remove incorrect character tag and you are done.

If the tag goes under General tags, then simply select Tags from top panel, search the tag in question and change the tag typ General -> Character.

I'd also like to take the moment to mention that the wiki is also a valuable resource. Someone who is trying hard to get characters tagged (A wonderful person!) is probably going to look up as much information as possible, so filling in some information on the character's wiki page would probably help quite a bit too.

I'd recommend keeping it simple. For example...

you can get to the wiki by clicking on the ? next to the tag in the tag list, then hitting 'edit' at the top. use and to link to another wiki page. :)
