I can confirm that inexperienced members at any fetish site can and do imitate what they see posted, sometimes to dangerous results. I heard from someone who'd read one of my short stories at another site (which no longer exists).
It was set in medieval Europe. I did a good bit of research on clothing, the structure of towns, torture in the name of the church, agriculture, and more. I learned that root vegetables were what farmers would be growing locally and that many veggies were once substantially smaller than they are now.
Turnips, for instance, were the size of present-day radishes. Long after this story was set, people started fooling around with crossbreeding crops for desired traits like resistance to rot and size, leading to present-day turnips, which range from the size of a large plum to a peach.
At one point the main character endures a turnip thrust where the sun don't shine. This would be a radish-sized turnip, unlikely to do a great deal of damage. (And in the story, it didn't.)
Naturally, this reader who thought the whole scene was hot bought himself a turnip. It took a good bit of lube and effort, and I think some alcohol, but he succeeded.
Uncooked turnips are hard, denser than a raw potato or apple. He could not get the turnip out and ended up in the ER. He contacted me with the oddest combination of fan letter and warning...
So yeah, if the mods would like us to flag the posts saying "I did X" when X seems both unlikely and unsafe, sure, we'd be happy to.
