They are filling up with comments about Michael Jackson.
This guy is BIG in Japan. I would bet at least 30% of his worldwide income came from there. For many fans, he can/could do no wrong.
But that's not what the boards are (hilariously) saying right now!
Example (my translation): "(They) or he could just continue to say, well, I was offered so many hundreds of thousands of dollars to just shut up, and even though I hated it, we slept together. You know, in America they do not have the custom as we have in Japan of mother, father and children sleeping in bed all together (AIT cultural explanation: so called "river" kanji character shape, with mom and dad on either side on the futon matress and 'junior', up until 10 years old, sleeping innocently in the middle). "Sleeping" over there in America, well, it means "having sex with". It seems to me there is no mistake Jackson had sex with them(him)." (unquote)
