Some information: 1 Galleries with some tags, like vore should give you a warning before you even see anything, if they don't YOU disabled it 2 Tag flagging exists 3 There is a script which allows you to see the tags on a gallery even on on the main page, use greasemonkey/tampermokey and install it https://pastebin.com/wRK25xyV
1. Actually, I don't believe vore delivers a warning window. Most of the time I get the window for guro or scat, but I see lots of vore without the "content warning: offensive for everyone" window.
