Don't think there needed to be two threads on this but this does raise concerns
Most all the beloved artists in the scene at large have drawn characters like the Pokémon girls, MHA cast, several One Piece girls who are "Canonically underage", and the list keeps going. If this dude wanted he can just go and get there pages nuked and in a fell swoop we lose Bill Vicious, BadPierrot, Klaudsan, etc. You can go on any tickle artist pages, find a character that meets this criteria and report it. You can even bullshit DA TOS on this for just about any character.
Even if they have other platforms, DeviantArt is generally the biggest for growth in this field (love it or hate it) so when an artist loses there DA, it inevitably leads to them quitting when less people are discovering them to pledge to there Patreon or commission them. Pixiv is the next best thing and doesn't have looming threat of deplatforming but ask yourself how often are you discovering new artists on Pixiv compared to DA and how often do artists on DA Post on there DA in comparison to posting on Pixiv.
Basically when beloved artists start losing presence and funding + new artists are too scared to start cause they fear the same thing will happen to them, then do not complain when we enter a content drought.
This is also such a faggot thing to do in general. It's one thing to think characters like say: Momo Yaoyorozu, with tits bigger then her head, getting her feet brushed till she cries and her belly licked till its red, is on the same level of loli porn, (I think if you see an anime character indistinguishable from the ones that are "canon adults" and think that's a child, that's on you). Going on a crusade to take advantage of a relatively new DA rule (Implemented in its current state about 2 or 3 years ago) to do this bullshit is also a shit thing to do (but that's ultimately on DeviantArt as a whole). But the fact that they feel confident enough to brag about it is where I think they have to be run off the platform too.
People who do that don't stop at what they're doing now, they will eventually be embolden to twist and exploit DA TOS to bend to there morals and eventually do the same on other platforms. They will eventually go after content you like and artists you like. If not nipped in the bud now they become a bigger problem later on so they should be scared off.
But the true reality is no one can be assed to stop people like this and its a hard to win battle. You can fuck this guy in particular but more competent people who have the same beliefs and will do the same bullshit while remaining anonymous can not be stopped. DeviantArt is ultimately a sinking ship. Rule of thumb is always archive tickle content cause there's never enough to satisfy and niche fetish porn is always on the verge of deletion.
If there's one thing I've concluded, it's that tickle fags need there own dedicated website to archive tickle content and encourage the creation of new stuff. Something that hosts Art, Videos, Literature and so on. Something where you can search for every work of a producer/artist, sort by franchise, character, year, What spots are targeted or even what spots are in focus, If its F/F, F/M, M/F. So On. Might do a full pitch another day but this is all I really have to say on this
