Google Translation:

It has been reported by several users that there are users who keep the torrents active to accumulate points with the speed capped.

This causes for a user that does not download and that cannot ask for seed by having a seeder, although "inactive".

Do not skip the upload, so long as there are no leechers, you will not remove bandwidth, and when there will be a raised ratio.

In the event that this happens again, users who are seedless without uploading will receive a warning, and if they relapse they will be expelled.
