Anything that involves a social media is not considered professional. Those are fake sites that claim they can get you jobs, just like linkedin.

All you have to do is set up your own site with portfolio theme and your business card linking to your portfolio.

Deviantart is garbage.

i think you're looking it wrong those places can get freelance jobs for sure but only if you're good enough they do however serve more as online portfolio once you get clients it's easier to send them a behance link to get them hooked imho.

What about Instagram? I've seen a lot of (wannabe) designers linking their IG handle, but who even looks there for designers? That place is only for attractive women. Or is it pushed upon us because Facebook forces everyone to join another """social""" network that will be abandoned in a few years, just like everything else?
