As VDHG said, Google frowns upon it and sometimes takes action. But most of the sites that I have seen that do this have never had any problems. Now on the other hand if you have a site that gets xxx,xxx,xxx hits a day; then they might actually look at your site.
Just be careful and not do too many and I don't THINK Google will abolish you from their indexing.
Go with your gut feeling on this,
