I asked this question: How can I check the version of Google Chrome without it upgrading itself without asking me?
Someone added a comment saying "why not unplug cable?" (perhaps worded differently, I don't have access to this comment anymore…), I replied to it, then some mods deleted the two comments (his/her question and my answer). Within the next few hours, someone else asked the same question in the comments and got 20 upvotes, which seems to show that the comment was interesting. Why did it got removed in the first place?
