For those with accounts on Mastodon instances (or instances running #Mastodon forks), this might be a good time to enable this in Preferences → Notifications:
☑️ Block direct messages from people you don't follow
Spammers seem to be (ab)using the DM functionality. Making it impossible to reach you if you do not follow a person makes that much less effective. And in general is just a good idea, IMVHO.
Tried to figure out how to do the same on #Calckey, but could not find the setting. Hjalp?
This setting should have been default-on, IMVHO.
But that's "water under the dam", quoting one of the best scenes in one of the most under-rated movies out there.
