Yes!! What makes you think most Google Adsense accounts get banned easily without apology from Google Adsense Team?
Few days ago, a very close dude was seriously complaining bitterly to me of what Google Adsense did to him, by banning his account with about $700(plus). To the lay man, that is pure wickedness.
Let's look at it from this angle, many bloggers are not even interested whether the click will be beneficiary to the Advertisers. All they demand for is a click. Well if you are such a person, you could likely be the next person to get Google shocker!
The fact that social medias such as Facebook, Twitter and Whatsapp have a way of generating you traffic and also getting you site up on the search engines should not warrant you the epitome to spam in there. We have so many spam on Facebook in particular. Such traffic you feel, you generate from Facebook groups and pages is not an organic traffic. Google respects organic traffic. Why don't you spend more time in generating something meaningful, work on SEO and lots of other stuffs to get real traffic, rather than joining Facebook groups and spamming them, to feel you're BLOGGING... YOU ARE DOING NOTHING!!!
Some weeks ago, a close pal was also into such act, he discovered his earnings were fluctuating, I told him to stop it. of which he did. Just in 24hours his earnings became stable. Google expect you to know how much they take invalid clicks serious, so you should know your visitors.
The bottom line here is, stop spamming social media and start creating original contents to generate organic traffic that would lead to nice earnings, than getting facebook traffic leading to too much invalid clicks... YOUR ADSENSE ACCOUNT COULD BE IN A GREAT DANGER BY DOING THAT...
