Hmmm.... I would never do the most popular template.
That's deliberately doing what all the lazy people are doing. Don't do what the lazy people are doing, spend 10 minutes to make your own template. BTW, the success rate is not as high if you're doing projects like that. I know it makes it easier, but really the only value I get from SX is the social networks stuff, some of the articles, and some of the bookmarks... Bang them out one at a time, and I know this sounds CRAZY but the people doing captcha for less than 1/4 of penny each really don't care that much about getting it right.
Doing CAPTCHAs manually will also raise your success rate. It's a pain in the ass. But I only want to do one run per week per project, rather than having to compensate for half-assed runs.
