Spam / Trolling Filtration Utility
Mass remove everything which was said by a particular user in a particular room.
cp ./config.example.js ./config.js- Edit config.js to make it use your username and access token, you can also change how far into history STFU will search (number of events).
node ./stfu.js <matrix_room_name> <matrix_handle>
For example, in case cjd is saying silly stuff in the Matrix HQ room, and you're an admin there, you can delete all of it.
node ./stfu.js '#matrix:matrix.org' '@cjd:matrix.org'
