Ask HN: Anyone else getting lots of Google Docs comment spam?
4 by mrblampo | 0 comments on Hacker News.
I.e. comments that are literal spam, from accounts I've never heard of, on documents I've never seen, but where I am tagged. And they always mention some Bitcoin transaction whose funds are now available, in or similar. Has anyone found a way to make this stop?
