Only 12 hours between an email and the account termination, with no real interaction and no way to change what seems not to be a serious problem.

That would change the time gap during responsible disclosure, Alphabet/Google is changing its metrics. I mean why only small developers would have to be mistreated.

If they play it that way, Android developers community can also report platform bugs to them - and go full disclosure (report the bug publicly) within 12 hours.
