Ask HN: Why does companies like Google act random and inhuman?

I used to run normal ads for some amazon niche affiliate sites and some apps install on playstore. Havent run any ads since 6+ months.

All of sudden I receieve email saying "Your Google Ads account xxx-xx-xxx has been suspended for violating our Circumventing Systems policy."

No clarity nothing. Which ad or what.I contacted them saying I havent run any ads since 6 months then why this ban?

Reply: Our stand remains same. Thats it no clarity on what was the issue or any thing so.
