On my end it's not there in place of my own ranking or anything, and doesn't affect my use of the site or ability to rank things, but I thought you might want to know there might be more of these from users trying to submit rankings in the past day.
It looks like "??? ????????" is actually a user's name. We've "fixed" it so that links to his profile actually go somewhere. Thanks for letting us know about this, though.
If ??? is an actual user, it's a very strange coincidence that ??? is the only other person on the site who ranked this movie I submitted - https://www.criticker.com/tv/American-Visions/ - and ranked it the same score as me shortly before me on that one glitchy day.
I don't know how or why, and maybe ??? does have their own rankings coincidentally, but their account also seems to be some kind of island for misfit rankings.
Yeah, that might very well be. Before I "fixed" it, that account had a blank internal identifier ... so misfit rankings (I like that phrase, btw) might easily have ended up assigned to that user.
