Honestly, I can't remember for sure the vehicles but there were more times when I found them missing after uploading. 2-3 times. And, if it's possible to check the history of more recent movies submitted by simple users (non-admins), please do. I am sure that you will find lots of deleted vehicles, he only validates what he likes, I think this fact is debatable by looking in his posts where there are only complains about pictures. I am not the only one whose pictures are deleted frequently. Maybe some feature would be useful where you (the webmaster) can see what was accepted or not.
Anyway, all that matters is that he deletes the vehicles we're sending, which should not be allowed.
