Google Adsense says my traffic is fake – it’s not!

Recently Google closed my Adsense account
(Not that I care for it!) -
Saying my traffic is fake.

It is not.

I get over 250,000 views to one of my websites – each month.
And these are all from social media.

I have no need to cheat.
Yet Google says this.

I find it ludicrous.
