It's just adnauseum.
That never made any sense to me. Sure, if you convert a significant amount of people to spamming ad clicks you reduce the value of each click but that just means advertisers will pay less per click. It also has zero effect if they use other metrics, if you pay on conversion rate (number of signups/paying customers) click spam doesn't matter.
There is some value in messing with data by clicking everything but if you never see ads anyway that data isn't worth a whole lot.
