You should give this a try: www.flurl.com
No idea how they do it, but their service is free of charge as for now. Hotlinking to forums is allowed. Both anonymous uploading and registered uploading (get an own account to keep your uploads on their servers for longer period of time, add your own html and more...) is possible.
Allowed file extensions: (max size 10mb) allowed wmv, asf, mpeg, mpg, avi, mov, rm, ram, rmvb, 3gp, flv, mp4, swf,j pg, gif, mp3, wav. No restrictions on sex or porn (so far). Videos can be categorized. Extensible celebrity category available allready! As far as I could detect, there are no upload- or download restrictions implied yet.
There is a forum which comes with their services as well. It has a help subboard and other helpful stuff on it: Flurl.com Forums.
For a "real" anonymous upload of videos to their services I suggest the use of Anonymouse.org. Anonymouse works much like an anonymous proxy server hiding your real ip adress and making the video origin untracable (important if you care about possible copyrigt implications of your uploads!
). Uploading vids this way may take a little longer tho.
So, despite my suggestion to use their service in order to get 'real' anonymity I have to reommend the opposite now. Nevertheless I believe it comes in handy for some purposes. That's why I don't delete their link from my prior thread.
