Google is notorious for sending DMCA notices to takedown private videos on YouTube. E.g. on YouTube I often receive DMCA notices for video I took when some music was around: clubs, concerts, bars, street performers, video game screencast, friend singing a popular song while taking a dump, etc. I even received a DMCA for a video containing white noise, so no video is safe.
Can Google send me DMCA notices to takedown private videos on Google+? My Google+ is synchronized with my phones and I use my Google+ account as a backup, hence the question.
