I finally got fed up with people using Scripting News to post the same off-topic comments over and over. It's not just that one person is being a broken record, there's a whole cadre of people who feel they need to be heard yet have nothing to say. They repeat themselves with very simple thoughts. Apple is great, Flash sucks, etc etc ad nauseum. They can "prove" it. If you don't like it it's because they disagree with you not because you've heard it a million times and didn't care the first time.
So if I ask a question that isn't resolved by a simple Neener Neener response, yet people post them -- my solution is to do what Apple does with Flash content -- off to the bit bucket. If, after I ask you to stop, you continue to do so -- I block you. If after blocking you here, you hassle me on Twitter, then I block you there. I don't give a shit who you are, if you're the Pope's long-lost brother, or the Dalai Lama or the chairman of the Republican Party. Goodbye. Please!
