I did think of that. There's a problem with that idea, however. I'd like to be able to put this on my resume to show people I've been doing at least something with my time, and a job like that is kind of unethical to say the least.
I've also been looking at fact-checking and proofreading stuff, but it's a little hard to sort the honest opportunities (if there are any) from the crap. One website wanted me to install keystroke and screen-capture software before it even let me consider looking for jobs. I mean Jesus.
