Now this is what I call an informative post..Thank you for this. I've been looking everywhere for a detailed explanation of why many tracker banning Bitcomet. Glad to see a knowledgable person here in this community. I also have read the report in the link you provide and there is 1 thing that I didn't really get,it's about what you suggested to the writer of the repott;
"SUMMATION: Simply put, the BitTorrent protocol does not work that way. The tracker does not inform seeders that certain peers have preference or priority. BitComet user XSTREM suggested to me that BitComet may send a “Completed” announce message when the user elects to download only a few files from a torrent. He suggests that some tracker managers may be using that message in performing user-accounting".
What is this "completed announce message" thing? I'm trying to understand the concept of this client so as you said before I (and other Bitcomet's user) know how to say something to defend Bitcomet with a proven fact whenever someone state a wrong statement about Bitcomet.
