I'm going to make a fake craigslist post
Why do you want to make a fake craigslist post?
So I can see if there's anyone in my area looking for a same sex partner.
It is rude to try and lead someone on like that. You don't want to upset the person or make them feel embarrassed.
I don't mind. It's not like anyone's going to meet me.
That is not a nice thing to do. It is rude to try and trick people. It will hurt their feelings and you will end up feeling guilty about it.
