A fake click pays as a genuine click. That is why I advise everyone to use a decent adblocker when surfing the Interwebs to be better protected against malvertisers and malicious ad-clicks.
Google & unmask parasites has something to reveal on the matter here:

See for the sucuri flagged link: https://www.virustotal.com/nl/url/5e2b779a7cb2f11a48c9cb14199b39ab742c09723976346e1ce22ae9624520e4/analysis/
and no-one to detect: https://www.virustotal.com/nl/file/7333687ac7129d907a8d64104fe98566c83bf45646a97bcc99318604718d8dfe/analysis/1423669601/
The real non-injected code can be seen here, but for me that link comes blocked by my Google chrome script blocker extension, uMatrix as it prevents the following page from loading:
-https://help.luminate.com/kb/merchant-solutions/SLN18465.html?impressions=true
And the uMatrix reports: “Go back”. As all of the web is just one ad-launching litany and browser-user profiling tracking machine, the adware marketing Twilight zone is ever expanding (the bad ads, the good ads and the ugly ads), often Google and Yahoo turn a blind eye and those that facilitate are often innocent to the abuse and are not the bad criminal players abusing their trust relationship.
