Ask HN: Is Google disabling accounts for using gws CLI with OpenClaw?

I installed gws cli for my gmail account and asked OpenClaw to check it 3 times a day and send me summaries. It worked well for several days. Today, I got an email from Google saying that my account was disabled for violating Google's policies. I had to sign in to appeal it. I signed it and before I could submit the appeal, my account was restored. Now, I'm wondering what the possible violation might be.

Any thoughts?
