It is not completely dead yet.... some pages still work, just all the personal account pages are blanked out. I guess this is done intentionally to avoid more flooding with bad payout requests and support messages.

For sure whining and going their nerves with useless messages and mails isn't going to help. I hope they are still trying to fix the data and do payouts when they have been able to. After all they are from Russia and have a lot of Russian customers. I wouldn't dare to take the money and run away in Russia.

This is a page, which still is active: https://50btc.com/analytics
