Why is that shot deleted each time? We cant even see who posted it, and I'd like to tell her/him this is a great snapshot and I wouldnt vote for its deletion. What is wrong with you people? There are snapshots a lot worse than this one that hasn't been deleted...
There seems to be a bug with this snapshot. It's not deleted by users. But since no one can access its page (Error 500), there is no vote... thus it stays at 0/10 and doesn't make it to Feature Films section (which is logical). The user responsible for this shot keeps uploading it, hoping the Error 500 message will eventually disappear, I guess... But actually, there's nothing wrong with us people (not on this one anyway). There's just something wrong with the site and/or the snapshot.
Right now it's impossible to block deletion. If 5 users have voted for deletion, the shot is deleted.
WTM creators are working on implementing email notifications in order to give explanations to the uploader when a shot is deleted before the usual 48hrs. But as long as this feature is not available, every uploader should keep an eye on his/her submitted snapshots, so that he/she knows why some snapshot is about to be deleted.
Once the 5 deletions-votes have been made, there's no way for us users to find out why.
But if you really wanna know, and if you still have those shots on you computer, you could upload them somewhere (Imageshack, Photobucket, ...) and post them here. Then we could try to guess (or remember) why they've been voted for deletion.
