How would they enforce this on open source projects without companies behind them?

This doesn’t require the user to be able to block, it’s required that there is the ability to block a user from the system in general.

Its a surprise to me that a reddit post or any kind of random text blurb can be used as an admission of anything. What if the guy simply says I made all that up for fun? There is no requirement for text written on the internet to be under oath. Edit: fixed spelling oauth -> oath ;)
