One of Bitcoin’s key communication tools used to discuss potential protocol changes was knocked out for several hours starting on April 2, with one moderator speculating it may have been a targeted attack assisted by bots.
For several hours across April 2 and 3, Bitcoin core developers and researchers were unable to interact on Google Groups after Google banned the group for spam.
“Bitcoin Development Mailing List has been identified as containing spam, malware, or other malicious content,” Google’s warning stated at the time.

Bitcoin Core developer Bryan Bishop told Cointelegraph that the ban may have been triggered by individuals or bots mass-reporting the Bitcoin mailing list from multiple accounts.
