Since the first half of 2011, some seedbox users appear to team up and abuse the upload (discounted download) system. Things are getting worse recently. These users upload torrents and download from each other, only to improve their stats rather than to share within the community. Their torrents usually die within 2 weeks. To regulate uploading and improve the lifespan of torrents, the staff has decided to punish abusers with the following abusers:
1. Seedbox users who concentrate on downloading large torrents (Blu-ray disks, TV packs, etc.), stop seeding before regular users (who don’t use seedbox) can even finish downloading the torrent.
2. Seedbox users who mainly upload large torrents (Blu-ray disks, TV packs, etc.), and their torrents are downloaded mainly by other seedbox users. These users as a group stop seeding as soon as they finish.
3. Other abusers with similar behaviors, confirmed by CHDBits staff.
Starting today, members are encouraged to report abusers to staff through PMs. Once confirmed, bonus points will be awarded to the informers.
CHDBits reserves the rights to change the definition of abusing behaviors .
