Those fake files don't bother me, I have a delete button. Use it every time. What is bothersome is those who keep those files in their systems! Waste of space and others time when their hassled with them. If all would just delete them right away, this problem wouldn't be as bad. I find most hosts with these files in their possession usually have more than one. With experience you learn to recognize these based on file size, the date, etc. If you get or have a file with unknown bitprint, help out, bitcollider it, and report on it (accurately). And if its bad, Delete it!
