No, I run into this with my Linode also. Basically any of the large VPS providers and some of the smallest are well known to other services for being used to automate scraping or other things. Linkedin is a great example of one that (used to anyway, haven't tried in a while) completely block any IP that was known to be from a VPS provider.

Nope, this is pretty common. I found out the hard way that Delta doesn’t allow access to their servers from my cloud hosted VPN, which is shitty considering airports are pretty VPN-heavy locations for me. They don’t seem interested in reconsidering this stance either.
