In the last two weeks my gdrive has been spammed with shared porn pdfs. It's not even being shared with the email address I use, it's being shared with my email without a full stop in the middle that Gmail ignores. Haven't looked into it much but apparently people have been asking for years for an option to only allow a doc to be shared from a know contact, Google has ignored this for a long time.
