My AdSense account was suspended three times because I had an exclamation mark in my ad. I closed my account after that. I am certain Google still tracks my account as "potential fraud" to this day.
Mine was permanently suspended with no recourse for that reason. Many years ago though.
What is their reasoning? Exclamation marks are in almost every print ad since the invention of the exclamation mark.
are exclamation marks not allowed or is that just some absurd mistake by them?
It's insane. They have the tooling to automatically lock my account because an ad doesn't follow the rules, but can't tell me while I'm making the ad? Why even let people submit invalid ads? What is the point of making it easy to sign up for adwords if new users are automatically banned in an hour?
