From This is Hell on birdsite:
"If you think capitalism is going to give up easily, you should see how many emails LinkedIn sends me per week despite not logging onto that site for like 5 years now." - https://twitter.com/thisishellradio/status/971207285056966656
@Greg the "good" news is that LinkedIn stops sending programmers email when you hit 40.
@joeyh @Greg Sadly, it doesn't even stop when you hit 60, change your profile to say 'Retired', and delete most of your work-related contacts!
Octodon is a nice general purpose instance.
