Google seems to be the only one that actually does it, regularly, with no warning or comment, to other people. Google also spreads bans to accounts it deems related, so your personal Google account is likely to be deleted at the same time as your GCP account. That includes your Gmail address and your phone login and cloud storage.

And vice versa. Company accounts have been deleted because an employee's personal account tripped Google's random number generator. Again, only Google does this.
