I have an LLLL.com (w/an X as a letter) parked, and chose a Chinese city on a whim to use as it's keyword.

Why is Baidu crawling my site so much? I have other domains with Asian cities or topics set as keywords that don't get crawled by Baidu at all.

It brings a little traffic from Japan...but just wasn't sure what to make of it...if anything at all. Thanks.
