Google in general has become far more loose on spam, from spam emails now showing on my Google calendar, to being added to projects where I cannot remove myself. They open up quite a lot of security holes and seem not be taking it seriously at all. I feel like this year for me has been some of the worst in a while. The amount of stuff I report everyday is considerable. I've been added to other drives in the past just you and I'm trying to find out how to move away from Google because of this issue. They are too big to care, but I've seen other platforms open up unfortunately it's hard to get away from the convenience of Google. Personally I think if you can move your stuff and create a backup account somewhere else it's probably a good idea too.
