I don't think it's your comment that triggered what's happening.

Khal's post title and content are clearly about witnesses. I guess we can all agree on what we can take away from the video: "Check out what the witnesses you vote for are doing.". Your comments in the video were totally fine.

The irony is that at that very moment, and for some time already, Khal was not checking what their own witness was (not) doing i.e. missing blocks. On top of that, it lasted for days after the video was published.

Then came his reaction when we started talking about it...
