It’d make sense for these to still be available to filter by (though probably best listed at the bottom) so that users can still see logs for those actions from the past, rather than having to scroll through the pages for ages to see them.
These filters should stay because people may want to look back on old actions they did with clans. A staff member on a different thread actually said why these audit log filters are still shown and why Tix still have to be shown in the transaction log:
Agreed, I doubt people will be actively looking at audit logs from clans so it is probably best they are shown at the bottom letting the more actively used filters be more accessible at the top.
I feel like another solution would be to automatically hide all obsolete filters (such as these clan ones) for any new group, but keep them for older groups. Or, as another solution, keep these obsolete filters for groups that have actions of these types, and hide it for those that don’t.
Right now they just clutter the space, would definitely be nice to see it cleaned up a bit.
