Hmmm I thought the original thread title was pretty badly-chosen (although it's interesting that it managed to survive four whole years unmolested.) But I'm not sure I like the idea of someone changing the thread title to a different word entirely. Like it or not, that's the word the OP chose to use to convey the meaning they wanted to convey. If it isn't acceptable then surely blanking it out would be better than substituting a completely different word with a different meaning. I wouldn't like to see that done to one of my posts.
"Destroyed" dosn't even have the same meaning. You can accidentally destroy something, after all. Whereas the original word clearly means to do something with intent.
