@FrailLeaf @sam ok in mix.exs in /opt/pleroma or akkoma or whatever find the line where it says {:linkify, somegayshit} and replace it with
{:linkify,
git: "https://gitgud.io/mintplg/linkify.git",
branch: "domain-mention-parsing-fix"},

similarly in the mix.lock file, replace the linkify line with:
"linkify": {:git, "https://gitgud.io/mintplg/linkify.git", "91e313e6532aaf31c5771132b5b62c755a34a106", [branch: "domain-mention-parsing-fix"]},

the run mix deps.get etc. These are mint's - you could also use sam's branch.
