Is there really any difference between the tags fake_rabbit_ears and bunny_ears_(cosmetic)?
The latter has much less of a tag presence (105 for BEC vs 1711 for FRE), but without digging deep into tagging histories just "nuke it" or "merge into FRE" seems to me like it might be questionable, especially if there is some noteworthy difference between them (doesn't seem so at a glance).
