Maybe this technique has already been used, but I just thought about this. Do you think you can make some decent money, Like a few bucks a week or so by using your affiliates and yahoo answer. People may ask where to buy this and stuff, and you just post your link. What do you guys think?
You can do it occasionally, overdo it, and/or do it when it's not relevant and - surprise, surprise - you'll be flagged as spam and deleted.
I guess a way around this, or at least to reduce your chances, would be to maybe list 2-3 sources for the product with only one as an affiliate link. Chances are a person will click both/all 3 and you'll plant the cookie for future amazon purchases even if they don't buy it there and then.
Yahoo! Answers have clamped down a lot on posting of links. You can get away with it if you are subtle but if you do it repeatedly from a single account or in a blatant fashion then the posts are usually deleted while they are still warm.
