The bulk update request #12117 has been approved by @nonamethanks.
sitting on_bed (the two tag combination) has 4 times the results, and it's 100% overlap, so there's not even an excuse of more precise results. It's weird that we even have this tag. The wiki mentions that it's for characters sitting on the bedside, but it's delusional to think that it could ever work with a tag named like this.
Worth noting that we also have bedside with a hundred or so posts under it.
