Well I suppose that depends on what you would expect from the account?
I can't draw to save my life so I can't really speak for posting anything on pixiv.
Some features you have with an account are bookmarks and following an artist (so that their activity will show on your feed).
There are definitely some fanart gems hiding in pixiv (such as
this for example). Though I do not think it is an ideal site to look for SessKag if that is particularly what interests you. Unfortunately this pairing doesn't have much of a fanbase in Japan.
