i strongly recommend that people add things like “gender critical”, “radfem”, “radical feminism”, “terf”, and “terfsafe” to their filtered tags. tumblr’s blacklist system will hide reblogged posts if the op put one of your filtered tags on it. this is a really easy way to not accidentally reblog posts by transmisogynists so often. it filters posts both on desktop and on mobile. and you can always click to view the post and double check the op if you want.
on mobile: go to settings > general settings > filtering > +new
on desktop: settings > account > scroll down to filtering and click the lil pencil
