well, it takes seconds to upload a torrent, I uploaded much larger images in the same threads and had no problem. Then again, I haven't had the problem again. Usually double posts (like I had earlier in this thread) are due to a timeout of some sort, which could be Tor switching nodes just like you said.
Can we at least get back the option to delete our own posts or do we just have to report them when this happens. Hard to see how having the ability to delete your own post would cause the staff problems.
