Yes, there are some U18s who are mature and sensible. And, yes, equally, there are some over 18s who are immature and idiotic.
But what I was getting at was the fact that getDare has always been a strict site when it comes to S/M. This website allows 18+ people only to engage in SM in the SM Area.
Under 18s are not allowed to request any Masters or slaves anywhere - do it in your signature, it gets removed.
However, there are threads such as "My Master wants to punish me hard - 14/m" and nobody really bats an eyelid. I'm not saying getDare should ban or anything, but when more and more appear, it appears as though the site doesn't mind underage slaves as long as they didn't begin on getDare, which is still a little irresponsible.
So all your talk about "omg why can't you be under 18 to be in BDSM yadda yadda" sorta misses the point somewhat.
