deactivating your linkedin 
also i do remember that thread. it was a salesforce certification which is some snake oil shit for sure.
Oy. That's even worse.
I only log into linkedin in order to accept connections with people I know.
I liked it for a while. I got a couple of jobs from it, including my current one that I've been at for 5 years.
But now it's like Facebook Lite and people just post memes or copy/pasted articles, and any of the job offers I get are for shit sales, call center, or temp/contract jobs. So I haven't been on there in quite a while.
