So within the last 5-6 months, but exponentially more since FA's big 'what is considered cub' change, I've been seeing a lot of people just mass tag changing pictures on ANYTHING that resembles short characters. Cats, kobolds, pokemon (non baby), dogs, etc. Doesn't matter if it's adult lore, if the image has obviously defined adult boobs, if the image itself has an age in it, or even if it's on FA after the mass change recently, people will see short character and just give it an instant cub/young/teen tag. Most of these people I've seen personally are alt accounts that were banned for, what I assume is mass changing tags which are not accurate, such as changing a specific tag on a specific image, getting banned, and doing it again and again with multiple accounts. I've seen quite a few posts that have well over 20 edits by the same person using alt accounts over and over, as if they have a vendetta against that specific post or something.
Now, I understand that e6 doesn't have enough staff to actively stop people from false updating tags to suit their preferences, so I have some ideas:
#1. New accounts aren't able to tag change for X amount of days. Such as 30, 60, or even 90 days. This will prevent people who make new accounts just to tag change or do other things. They could do it after the time period ends, but I think waiting 1-2 months will deter most of them.
#1.25. Accounts that were banned would have all tag changes done from that account reversed (but this seems difficult to implement).
#1.5. After the period ends, these semi-new accounts will only be able to do a certain amount of tag edits per day, such as 5 or 10, for 30 days, then they will be moved into a fully accessible account which has no limits (except for posting images which is a separate mechanic).
#2. Recently created posts will have a window of time where all tags can be changed by whoever to whatever is required for that post for 2-3 days, before applying #1.
#3. People who upload the images have full reign at all times (unless tags are locked by a staff member) to change the tags to what they deem to be ideal, rather they be the artist or someone just uploading the art for the artist.
#3.5. People who upload art can set a partial lock on certain tags, or even partially ban certain tags, especially if their image is clearly of adult nature. So they could ban the cub tag, and the only people who could change that is admins or people of high positive tag changing.
#4. Accounts that have a high positive tag rating for changing tags over a longer period of time without them getting mass changed (because they mis-tagged) will have a significantly lower tag change time, or possibly not one at all.
I know this is a lot and none of these will probably be implemented, but this is what I personally think would be the best ways to prevent the massive influx of bad taggers.
