Normally I just stayed logged in when I'm on my computer at home, but everywhere else I log in through my profile page.
I saw it a couple times that it looked like stuff (in this case whatever was under "New Deviations") was replaced with a blank DA thumbnail and the title just said "Deleted Content".
But when I signed in everything was hunky-dorey (as in a-ok). I was able to get it show the deleted content another time, so I logged out and went to the main page to see if it was just mine or affecting others. It wasn't, and when I went back to my profile it was alright.
I know there's a feature to let your stuff only be viewable if you log into DA, but to my knowledge I don't think I have that.
So...yeah that's all.
