I'm afraid I can't find the source, so take this with a grain of salt. But I seem to remember reading a few years ago about a small company having all their employee's Google accounts suspended because one of them had previously been banned for something, and his banned account then "infected" any other accounts it came into contact with, like common projects.

I question whether separate accounts would help, Google's automated systems probably connect them and bans all of them anyway.
