According to some users, tagging disembodied limbs with counter tags is a thing that shouldn't be done, not even with 1other (post #6176485 being a recent example that led to the creation of this topic). This, in my opinion, goes against one of the reasons the 1other family tags were created, and this gets even worse on posts tagged with 1girl + hetero but not any *boy(s) tag. As far as I know there aren't any hard rules what to do in these situations so I wanted to get opinions on it (I'm firmly in the "tag it" camp 99% of the time).
topic #21237 is related to this.
