I upvoted your comment, but I've seen this comment pop up many times on a variety of blogs. You need to find a different way, because spamming isn't going to work.

You should just start making some decent comments, and you'll earn more that way when people upvote you because they like what you have to say.

And enter some contests. Plenty of those going on every week.

Help some people out first and you might be surprised at the help you get in return when you need it.
