Eyuch. I've met plenty of creepers online - but not actually on here.
I actually started out roleplaying on this website called Stardoll when I was younger - they were pathetically stringent on their swear filters (Seriously, you couldn't write a something like "blahblahblah kick. I'll blahblahblah..." Because one could actually find the word kill in there - see the bold [Yes, they were that pedantic over it]! Kill was a bad word not to be used! As was lick! And Hitler!?!? For some reason?!)
Anyways, long story short, despite these ridiculous and frankly hair-tearing-out-in-annoyance filters, people still managed to write pretty graphic sex scenes.
I remember RPing with one girl as she started having the characters get undressed and everything, and I was like... "Um... fade to black?"
And she was like: "Nah, let's write in detail the moanings and groanings, and the PENETRATION! :D"
I WAS LIKE 10 AT THIS POINT.
Fair to say I put my foot down, and avoided romance-plotlines with her at all costs. XD
