I've read that he's been sick again (...)
Where did you read this exactly?
Sometimes it looks like every time LL disappears with no explanation people would come up with all kinds of theories/speculations regarding his absence, but rarely anything is based on any solid source.
If that's true, I feel sorry for him and wish him speedy recovery, but his not the only person involved in running the site, and there's always a way to at least keep people updated on what's going on etc.
The campaign manager informed about that situation in the signature thread by quoting the private message from LL to him as far as I can see.

Hope LL is getting well already now as I can see that he is online today.
The escrow address for the campaign has been refilled and hopefully he will do the same for the hotwallet in the casino because the one who is complaining above is still not receiving his withdrawal.
