I see this site more as a hub of everything my little pony, if you want anything related to my little pony, Derpibooru’s become one of the best places to start. It’s not even exclusive to friendship is magic anymore, earlier generations seem welcome here too. To deal with your point about art, a quick look at “meta” shows a lot of posts that have garnered a lot of discussion, while having nothing at all to do with art.
For example, I can see an image by The Smiling Pony regarding feedback for the site. I can also see several screenshots of tags for images, with a discussion similar to the one we’re having right now inside of it too. It even has a suggestion about adding a pony to the image, to make it pony related, a cheap practice that should not count. It should be here if it’s important, and if there are people who like it, that should make it important to keep. I’m no fan of ticket, and I tried to use ticket as an example of something that the majority of people disliked. However, when checking the scores of the ticket pictures, I found that most of them have a pretty good score, or I just got lucky on my sample collection. Either way, a good lesson to take from that is that there is usually a surprising amount of people who like something that you don’t like. While I agree that “cum on toy” isn’t popular, I myself take no pleasure from seeing those pictures, I’ve had a look through some of the comments when Skoon posted some of earliest pictures of the genre. There are people who actually like this stuff, and they aren’t causing problems, why fuck them over?
In an attempt to highlight the point I was trying to make earlier, I found another tag that has had the response I was trying to look for. “fluffy pony grimdark”. That one has already had the response I’ve been looking for. It’s been hidden by default now, it’s still going strong, and I haven’t seen any “meta” posts whining about all the fluffy pony grimdark pictures that they keep seeing despite it being hidden. Out of sight, out of mind for those who don’t wish to see it, and people who either like or don’t care about it can still see it. There’s no issue there, why stop it with another tag that has become so rage inducing that it has repeated the cycle of fluffy pony grimdark (There was a vote on what to do with it I believe, can’t remember if it was a ponibooru or derpibooru thing).
As for your point about where we draw the line, why draw a line? If enough people want pictures of mlp dolls thrown from ever increasing heights (like off a high building), why stop them? People will see it, make a judgement on it, and then move on. If enough people from the community like the idea and run with it, let em have their fun. If not, it joins the rest of the garbage pile in “forced meme” or other things that lead to it being forgotten. I know I don’t particularly care about many of the fads that keep popping up around here (e.g the gravestone with celestia, rainbow dash’s two words etc), and I also don’t care for many of the non-pony fads that appear everywhere else (Harlem shake, caramelldansen, etc). I go through this site with all of the tags unhidden when possible. If I see something I don’t like, I move on. If I see enough of it despite moving on, I eventually block it. To date, I believe the only tag I ever hid was bronyetiquette, and that was due to it being a completely unfunny joke that someone pushed for far too long, and even that tag was unhidden at some point. If “cum on toy” was hidden by default, it would go the same way as fluffy pony grimdark, but perhaps with the people doing it for the sake of trolling stopping.
I don’t see any advantage of criminalising that tag when there’s a solution that makes a compromise that does not detract from either side. There’s even a precedent for this sort of tag with fluffy pony grimdark, and that didn’t sprout into any sort of drama fest due to it being hidden. If you want to see it, you can unhide the tag, and when the settings page is properly updated, you are even given the exact tag you need to use to unhide its contents. If you don’t want to see it, don’t unhide it, and don’t search for it. And if it’s hidden by default, then most of the people who get angry at seeing the images won’t see it anymore. The response to the pictures won’t be walls of anger, which means the trolls doing it for the reaction will stop, leaving the people who actually like it to create the content for it.
