I've been looking onto the stocks tag today and researched it via Wikipedia and I have to ask: should we add another tag that is related to the former tag?
According to Wikipedia, stocks are restraining devices that only restrain movement by the feet. The subject I was trying to mention the pillory, which is a restraining device that secures holes for the head and hands. Most images have them but are tagged as stocks.
Should "pillory" be a new sub-tag for bdsm be added? I'll respond whenever I can.
