Quoting replies to ads in a story

[lucy]

I'm writing a longish story/book in which one of the heroines goes about searching a Dom/me by posting ads online. Now I tried to come up with a few answers, but found it awfully hard to make them sound genuine.
The thought of taking some real answers to such ads has crossed my mind (changing them enough to make them unrecognizable) but I'm not sure whether that's acceptable. I think it isn't, but would like to hear more opinions.

Best ask the people who wrote the real answers if you can use them (the answers, not the people :p).

Gosh! That's brilliant. If only I had thought of that myself.

With their authors' permission it would be fine, of course, but you might get better results in here - perhaps you could post the ads and ask people to write suitable replies specifically for your story? Give a hint what sort of replies you're needing for the plot and let us help with the gaps.

Yeah I only saw POTCO ads like 3 years ago too. I was thinking about this the other day, they should put some up....
