Folks on Mastodon, to hide the current deluge of spam:
1. Settings -> Filters
2. Add new filter
3. Add a title (e.g., Spam)
4. Select all the context checkboxes
5. Set Filter Action to Hide Completely
6. Add the following keyword with a hash (#) before it: 診断メーカー

@TuutW Seems to be for me. Just tried it out :)
