If the prize was just some token prize as if to say thanks, then it would not change anything. If the prize on offer were big enough (e.g. $10,000.00), it would cause me to change a few things.
I would then see it more as a business, or at least treat it like one. I would keep controversy to my self, I would pander to the audience, and would probably make lots of statements that everyone would agree with.
Instead of thinking up ways to put forward my genuine opinions, I would think up clever and poetic ways of saying “pedofiles are bad / equal rights for all / retarded people are cool / etc.”
Instead of answering questions I am interested in, I would answer all questions, I would spend some time on researching things, and would prepare copy and paste snippets for top positioning on the page.
It would probably be beneficial to the site owners, I would generate more content that is suitable for any audience, but originality and honesty would suffer big time.
Also, I would do this all on a seperate new account, I would not like to associate my face with those words. In fact, I would probably put up an avatar of an attractive female and follow all the males in hope of reciprocation and more lurve.
Oh yea, I would probably get busy with IP’s and things, create loads of accounts and give my self lurve.
If I set my mind on the prize, I go for the prize.
