Specifically, I got hit on by some creepy dude online. He was my opponent in a Pokémon Showdown match. At the start he used the site's messaging system to PM me, to ask of I was interested in role play. I was pretty sure what he meant, but I hoped he meant the RP Chat Channel in Showdown or the Pokémon move "Role Play". Nope, he clarified, he meant romantic role play. Ew.
I told him that if creeping out the opposition was his strategy, it was a success. I then forfeited our match and closed the site.
And it seems like dealing with the advances of creepy dudes, both online and offline, is something I'll have to face for the rest of my life. I'm just processing this first, largely harmless, occurance. I'm also wishing I had stuck it out and crushed the little cretin in the match...
