No. When I attempted to create a LinkedIn a few years ago they flagged my account as spam and requested a photo ID. They will not get one from me.

GitHub under Microsoft also flagged a new-ish work related GitHub account as spam. They eventually reversed the suspension after four/five months. Luckily my day-to-day work does not have GitHub in the loop. On one occasion a co-worker did me a favor and submitted a PR for me.

* In LinkedIn's case I used some Czech in my profile. Maybe that made it seem suspicious.

* GitHub doesn't like when you delete a GitHub account, wait some amount of time, then create another GitHub account with the same email address.
