I made a post regarding a specific image that was having a 'cub' tag battle, and although while it was eventually fixed, it took weeks for it to happen, and that's honestly too long of a time for just a single image to get fixed by mods/admins/janitors, etc. I'm aware that they may have better things to do, but it's still an issue regardless.
I keep finding images that I have favorited that are very clearly not cub/young, but continuously get marked as such under the guise of "tag what you see" (I try to keep my favorites cub free because I'm not a pedophile and I don't want people to think I am one). It's honestly starting to get annoying at this point, and there really should be punishments for people who continuously change tags back and forth. Like temp bans for changing tags or something. Just today, I changed like 5-10 tags of very clearly non-young characters, like tsukino from monster hunter. She's a small cat. Small cats do not 100% of the time mean underaged, and it's pretty clear she isn't in those images.
Although one could argue that a riolu is considered a "baby" pokemon, and that it is entirely up to tag what you see to determine if its cub or not, but sometimes it's pretty obvious. Like dacad draws a fair amount of 'aged' up riolu's, but people don't seem to care about that. It's like on a similar spectrum of someone taking tails prower, and aging him up to be a very obvious adult, but people still mark him as a cub because that's what his canonical age is, regardless of the interpretation of the fan art drawn, and that's just not how it works.
I think the best way to fix tag battles is to make it so if you change a specific tag, you cannot change that tag again except in a specific time frame, like 1 hour in case you made a mistake in the tagging, else must go through a reporting process, per person. And the reason I think that would more or less fix it is because 9/10 times, the people who are changing the tags are the same person over and over, when another person removes said tag. It's almost like they are specifically watching that image, knowing someone will change it back, just to jump on it and go "no u". And then additionally, if a tag is added and removed 3 times in a row regardless of time, the post needs to be automatically flagged and checked by staff. This should stop most if not all, improper tag changing. And then if in the case a staff member misjudges the tagging and locks it, then the original artist can go on there and make a report about it.
Obviously this is on a larger scale than just my favorites, but I don't look at random cub porn to determine if I think it's of age or not.
