Google doesn't differentiate between any activity linked to the same account, and it's a viral thing so that "bad behaviour" by even vaguely associated accounts will "tar and feather" everything associated.

An example that came up was someone's GCP being wiped out because he was engaged in "ad theft". The guy had a personal video channel where he was uploading videos and then checking them for quality. Because he was a significant percentage of the viewer count, his account was flagged as "faking views to get ad revenue" and his online presence was nuked by Google. Email, VMs, YouTube channel, everything.
