I'm now working on authorised torrents and trusted users.
A torrent will be authorised if a group member posts it with the appropriate group tag.
For example, if the user "Holo" belonging to the group "Doki" posts a torrent tagged with [Doki], then this torrent will be marked as authorised.
Torrents tagged with a group uploaded by a user not belonging to that group will not be marked as authorised.
So if the user "Holo" not belonging to the group "Chihiro" posts a torrent tagged with [Chihiro], then this torrent will not be marked as authorised.
Because this system does not account for people such as
https://anidex.info/?page=user&id=8100, an alternate system will be used for these people.
Since these torrents don't belong to a group, the only way to deal with these will be to use a "Trusted User" system.
In order to become a trusted user, you need to have contributed a significant amount of good content to AniDex, such as
https://anidex.info/?page=user&id=7449 and
https://anidex.info/?page=user&id=8100.
Active groups will have an option of not allowing non group members to upload torrents containing their tag in future (exceptions will apply, eg if your group is long inactive, then others will be allowed to upload torrents containing your tag).
Please discuss below...
Edit: Scene style tagging (using a suffix of "-tag" as opposed to a prefix of [tag] is also supported)
