Well, yeah, any policy is going to only be as good as its enforcement makes it. We don’t throw away a safety tool because somebody who should have been banned a long time ago is misusing it to excuse genocide. Any rule will need to emphasize that it is a safety tool and not an “automatically win arguments” tool.

EDIT: not that we even have that option, of course. It’s here, presumably to stay, and we need to know how to use it. If we purposefully neuter it in order to justify a handful of edge cases (I think it’s just Velacron? These people tend to weed themselves out anyway) I feel we do more harm than good
