This is a short-term method with no long-term potential, but I can't dispute that it may work for a short period. You would be better off spending the Fiverr money on an SEO service or article for your website because at least it won't put your Adsense account at risk IMO. Once your Adsense account is banned, as you make new ones they will continue to be banned (even though it may take a couple months each time) so just know that by putting your Adsense account at risk it is not a one-time risk, it will last for the duration of your relationship with Adsense unless you have the ability to create footprint-less new Adsense accounts.
