As someone who still uses DA, its still usable imo. There's still issues with drama between users sometimes but it's okay.
Only major problem is their content laws. Obviously porn artists know they don't have a place there, but the PG-13 cheesecake artists always have to potentially deal with harassment and false reports from overly zealous fans of certain series who can't stand those artists 'perverting' their characters. Happens a lot with people who draw PG-13 RWBY art.
So I'd say if you're a SFW artist, DA is still usable, if you're a borderline NSFW artist, it can be dodgy depending on what series you draw cheesecake of.
