Allow labelers to set up custom report options.

[cyberrb25]

As a user of third party moderation systems, it seems a bit strange to have the report choices not match the moderation/labeling sets.

Just to explain where I'm coming from – I use ændra's XBlock Screenshot Labeler, which lets the moderation team label tweets with different tags for whether the images are screenshots from different places. However, when setting up a report, the options do not account for those labels, but other features that are completely unaccounted for. The only option would be to cite other and write up the reason and motivation.

And that could mean for the labeler that they have an uncontrolled firehouse of motivations, whereas the classifiable reasons are unused.

For those who would rather do the same as Bluesky's current way of moderation, those report options will help. For anybody else trying to do so, they might want to set up other kinds to help their own work (even if there is an other way to bucket out anything else).
