@Kirino @lina Oh, it'll work, it worked last time: for a while, every single post on FSE was tagged with "fediblock": https://git.freespeechextremist.com/gitweb/?p=fse;a=blob;f=lib/site/mrf/i_do_math_motherfucker_do_the_math_motherfucker.ex;h=bb1f153d282614fbd62c75cc241e1826ac63be85;hb=HEAD .

On the other hand, an MRF that rejects all posts with more than four hashtags might do the job faster.
