Read-read the post.

I wish I could, you totally changed your post without telling what you added and deleted. You even took out text that I quoted!

I pasted someone else's reply to a similar situation from years ago, and was in the process of editing when I posted it by mistake.

That is why you have the right to change your post. Of course lots of things can go wrong: you type slowly, your connection dropped, you logged out and forgot your password, but puh-lease don't expect me to believe this when I replied to your post almost an hour after you posted your first version. You had almost an hour to clean up your mistake!

I'm not even gonna reply on the rest you wrote, 'cause the chances are that you will change the post I am replying to right now again.

I edited immediately, but was unable to reach the site for some time. Hard to do much about it when the phone lines are down. I said to re-read the post specifically because it had changed and I'd not been able to fix the problem in time.
