Some information:
1 - Galleries with some tags should give you a warning before you even see anything, if they don't YOU disabled it
2 - Tag flagging exists
3 - You can block uploaders who mainly upload stuff you don't like
4 - 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
