I can't remember if I mentioned this one, but I actually found it a bit insulting. I write. An acquaintance has a small blog getting around ten views a week. They asked, well actually demanded, that I should write several articles a week for them for free for exposure. Apparently this is a favour from them to me, as it is practice, exposure, and "maybe then someone will pay me for my writing" and I'd be "a proper writer".
Ironically they actually learned I was a writer from seeing one of my articles in a newspaper, and I've been paid for my writing for years. I said a polite no, refrained from asking why on earth they wanted content from someone who is not "a proper writer", and am distancing myself from them to head off future requests.
To quote Harlan Ellison "people die from exposure."
