Yeah, I was very disappointed with that posting, which I ended up deleting after 15min. Every cell I wrote was deleted, and at least one person put up porn on it.
Is that coming from HN users or is there some sort of public search for public documents on Google that funnels trolls to it?
I'm pretty positive it was from HN users. I've shared other spreadsheets in the past publicly and never seen random people on them beyond the community with which I shared them.
If that is the case it is a disappointing development.
