Dude, you must be too stupid to understand the context of his post. Here's a small grammar lesson for you;

E.C said that last week you said that you LIVED in the UK BECAUSE YOU SAID IT LAST WEEK. He made "live" past tense, because he's saying that you made that comment IN THE PAST. He is NOT saying that last week you said that you lived in the UK when you were a kid. He's saying that last week you said that you WERE STILL LIVING in the UK, but for him to say that, he needed to post "live" into past tense, because as stated previously, that post of yours came in the past. YOU DID NOT MAKE THAT POST RIGHT THIS SECOND.

Before you get in debates about this kind of shit, you should try learning English first.
