1. You can blacklist uploaders who mainly upload stuff you don't like (in settings) 2. Tags can be watched, hidden and assigned weights (https://ehwiki.org/wiki/My_Tags) 3. Some tags should give you an warning before opening, unless you disabled it. (delete the nw cookie to enable it again)
I'm aware, that's why we have to add the tags in that case. Snuff doesn't require modpower iirc, so it should be fine. it's a hassle, but it is what it is. Would like an oral vore tag as well, but gotta work with exclusion. Gotta use what you got, don't rely on tags being added because they rarely add new ones. They recently did add some, but I wouldn't expect it to be a regular occurrence.
