I think this would need to be clearly labeled as an experimental builder so that it's clear that developers aren't on the hook for fixing it. It also means that the bot will need to be configured not to send mail to the blamelist.

Hello.
The terms-of-service outlined in https://reviews.llvm.org/D62020#1505233 are being violated by this bot.
Either un-GM it, or silence it, or remove the bot.
