Hello,

thanks for all the warm words.  I very much appreciated them.

I have to say, I already got a reasonable reward from bc.i.  Also many thanks to the satoshilabs people who offered me a new trezor (could be handy as a backup next time).  If you still want to donate I added one of my bitcoin addresses to the signature.  And if you ever need to store 267 BTC safely for a few days , you can get a trezor here.

To answer some of the questions:

In principle, it should be safe to use blockchain again, but I still see some bad transactions.  The last occurred six hours ago. There are only very few now and the guess is that this is because of browser cache issues.  So clear your browser cache and reload the blockchain page.  

If you generated a new address on blockchain in the night from Dec. 7/8 (UTC) before the bug was fixed, you should consider this as broken.  
Even if it is not on my list.  The same holds for every address you sent money from during that period using the blockchain service.  If you accessed the website during that period, you may have gotten the buggy script in your browser cache, so you may still be affected if you later created a new address or sent money.  I'm not sure of the end of the time window.  The first buggy transaction occured Dec. 7 21:53:26 UTC.  

If you lost money during the last days you can reclaim it by writing to the blockchain support.  They can see whether your claim is valid and will refund you.  That said, I'm not affiliated with blockchain.info  (I just returned them their money).

For the record, I used these addresses:

1L7gfUxCY5bDmzp1xA6CjA3qXZwsbzWGbG
1HdqdZudnV681xapavSJp3LqaCcJn12eSE
1EjXAe3WRqipdQdP5qeESjZRhxLVfe6cJ7
17TifxwuGSor7woQ64gL57KJzwPAjSf3Qa

the money to these addresses have been returned.

I see that there are several different 1xy... addresses related with this incident.  These are not mine.

I hope that all remaining issues will be resolved soon.
