Adobe must be thinning the collection.  I've gotten numerous files removed lately, most approved years ago.  Small numbers: 2 here, 4 there, etc.  Many are city skylines and generic (in my opinion) city or travel shots.  From what I can gather, the reason given is these clips "contain elements that appear to be protected by intellectual property (IP) laws, so we can't accept it into our collection".

Guess they had some legal issues and are taking steps to avoid further problems.  But looking at some of the shots of mine they're removing, I think they're tightening the screws a bit too much.

I just wish I knew more details as to why this is happening.  Trying to find these seemingly random removals in the sea of "not accepted" clips that are already in my dashboard are nearly impossible.

i got this email too, for the 2nd time ever.  there were 2 images removed this time due to an "audit."  they only showed 1 thumbnail with a link to my rejected images for more info.  it's utterly impossible to figure out what the other image is because they're sorted by date and i have no clue when it's from.  whatever man I'm not upset, just don't block my account for totally normal submissions that you should have rejected yourself the first time.
