Thought ad limit is as a result of unverified traffic source?No..
If you still want to do that, buy one account and make atleast $100 ASAP before ad limit placed on your site.
If you want to get banned? Google is not that dumb. You can trick it with more sophisticated stuff but getting maybe 50-100% CTR is just a red flag. Also, if you just have couple of spikes and never else any real traffic, also unrealistic....Is safe get adsense clicks using micro job site ?
