What file uploads work?

Nearly all media file types (mp3, wma, avi, mov, jpg, gif, swf, etc.) can be uploaded just fine. The major problems are files that could potentially be a security risk or might abuse the terms of service. For example, PBwiki was being hit with spammers who were just uploading .html files with links to various weight-loss drugs and whatnot, and so files such as .html, .htm, .js, etc. are filtered. Because of the complexity of the filtering mechanism, however, the answer isn't exactly easy.

As Nathan Schmidt, our CTO, explains in this thread, a lot of factors go into the filtering algorithm.

Sorry for the not-quite-so-simple explanation, but I hope it answers your question at least a little!
