36. Why can I not delete my own posts?
If users could delete their own posts then if you got hacked you could lose all your images, that's the main reason.
Also when you upload here you donate to the great library of porn that Rule34 is, just like a library you can't just remove the books willy nilly.
However, if you have a good reason to remove an image, please flag for deletion with your reason, for example, duplicate, or uploading a better version, or perhaps you uploaded something against our terms of service by mistake, or perhaps you are the copyright holder.
Otherwise, you can also site mail (not email) an admin and ask, giving a reasonable reason for deletion, if you wish to remove all your images for no reason but you want to, you will be turned down.
