Afaik Google has no strict policy against paid traffic. They just don't like Google adwords arbitrage (paying adwords to get traffic to an adsense site, marvellous

), and they don't like made-for-adsense (mfa) websites in general. But the TOS does not say you can't buy traffic for your mfa website. Can anyone copy/paste a policy against it from the TOS?
PS. just because I'm saying there's no strict policy in the TOS as far as I know, that doesn't mean I'm suggesting you should buy traffic for an MFA website. However if you have a legit, good website which just happens to do adsense as well I don't see any objection in buying traffic. Don't mistake buying traffic (campagin based) for buying incoming links though
