The number of phrases that can be muted is limited to 200 for some reason. Ridiculous but would be less of a problem if they bothered to parse text like any CS101 student can, so when one mutes a word like 'draft,' one wouldn't also have to mute every permutation like 'drafts,' 'drafted,' & 'drafting' just to avoid catastrophist twts. And the "show fewer twts like this" button does absolutely nothing, & there's no option to "show fewer QTs" of this person/twt, even if they're already blocked.
