Thank you for keeping an eye on this we have re-iterated this issue with our collaborators at Cornell & asked them to make sure they check and remove the bad movies. It seems they have been removing a few hundred a week.
I believe this is going slower than initially expected (and there are more bad movies than expected!), and all movies still need to be double-checked & manually removed (and they only have a couple people working on it - which is the whole reason we need Stall Catchers in the end, really )
In any case, they seem to be on top of it as much as they can be, an hopefully you will be seeing less and less bad movies now.
Also hopefully we will soon have better methods for generating movies faster without so much unclean data! (This issue has been really frustrating for us too )
Thank you again, and our greatest apologies to you and all the catchers who have encountered these repeatedly - hopefully we can avoid anything like that in the future!
