Looks like someone put a challenge for breaking weak signatures:

The first output used k=1 when spent. This was broken immediately by a bot.
The second output used the same k as a previous transaction of 19iAvuzfb8uH2SZLYcbb5wtbBZdn1o3vRm. The latter is probably a weak brainwallet or something similar. I didn't break it though. amaclin, can you explain?
The third output has k=private key. I solved the challenge and collected.
The fourth output is still unsolved.
The other four outputs are not yet spent. I guess we still have to wait for the challenge. Or maybe the address is weak for some other reason.
