Looks like the magical mystery miner is now connected only to other miners, thus appearing as Eligius and Deepbit on Blockchain.info.
The faster you tell other miners about your block, the less chance they'll make the same block. The faster you know, the less chance you'll make the same block. Reduces the chance of an orphan which is better for profit for both.

On edit:  looks like the mystery miner supports p2sh.

coinbase: 040c350b1a028d06062f503253482f
decoded:  5�/P2SH/

Where can this information be found?

Your link doesn't support anything you just said.

You don't seem to pay much attention.  Within approx 2 hours and merely 4 posts, I posted two links right here in this thread.  You replied to each of them, so you had a chance to open them.  Generally I don't like to repeat myself, but I hear you asking for me to elaborate and so I will explain again (this time; and more to the point hopefully).

The first link was: https://bitcointalk.org/index.php?topic=66514.msg775108#msg775108

It supports two of the claims, namely a) BIP16 renders old clients vulnerable to DoS attacks and b) not processing TXs "hot fixes" this threat until the client software can be updated.  If you think the link isn't supportive enough for claim a) because I said it, then please read the whole thread or at least the part which explains how exactly the exploit works: https://bitcointalk.org/index.php?topic=66514.msg772311#msg772311

The second link was: https://bitcointalk.org/index.php?topic=60950.msg711055#msg711055

It supports the other claim, namely that those who can't update their client are excluded from voting (for/against BIP16).  If you are in a hurry, you may want to skip all but the last paragraph.

As a technical person, my summary is:

Question: Is updating necessary?  Answer: no.  Wait, maybe.  Wait, YES! You may be DoS'ed by malicious TXs.

Question: Can I gain more time by voting against?  Answer:  No. You must update first, then you may vote.

This means: Solve your own problems yourself.

And that's all what happened, problems have been solved.  There is no conspiracy behind it.

And a personal comment, if I may add:

I really mean just this, without personal attitude.  The project is great and the board is great too.  You may think I am opposing multisig or P2SH or whatever.  The only thing I am opposing here is the update spiral / time pressure.

A more compatible transition may exist, and people could try to find it.  I know I could find one if I tried.  But the opposition between LukeJr and "the world" shows me that any such attempt is waste.  The transition to multisig must happen in the way it is supposed to happen.  A bit rougher maybe than desired (by all parties), but nonetheless.  And to my delight, I also hear that a smoother compatibility path is prepared for future protocol changes (fingers crossed).

jetmine let me slow it way down for you....

1) a no vote is a vote against.  going forward requires a majority of hashing power.  if "mystery miner" was against p2sh he could simply no-vote.  

2) excluding transaction does absolutely nothing.  One can no vote or even vote against AND include transactions.  One can vote for p2sh and exclude transactions.  Your claim was MysterMiner was excluding transactions because he had to in order to "defend" against p2sh.  Nothing you linked to supported that claim.

3) Ironically "myster miner" supports p2sh.  Smiley  Isn't that just icing on the cake.  Now likely he is "supporting p2sh" simply by default using the latest bitcoind but it kinda blows away your entire argument.  If you had been objective you would have simply looked at his coinbase transactions to see what is there.

Great, I see it took you less than 4 minutes to reply.  No wonder that you skipped over all I said, including the question about where to see that coinbase info.  So I went to find out myself.  And then I looked for the IP in question, which you can find in the tread topic if you have any doubts.  And surprise, this is what I found in blocks 170010, 170009, 170003, 169993, 169991:

040c350b1a0332f607
(decoded)  52�

040c350b1a0319af07
(decoded)  5�

040c350b1a03a4a107
(decoded)  5��

040c350b1a03d52c08
(decoded)  5�,

040c350b1a034d3708
(decoded)  5M7

There.

And, while you've edited your post and removed the insulting part about me "go back and delete my offtopic and lengthy posts", maybe it's your turn now to do just that.  Or not.  You won't read more from me in this thread.  It's not that important.

Excluding TXes won't make sense as anti-BIP16 defense because MM still should correctly decide on which other blocks she should build next ones.

It is causing confusion because it looks like Deepbit supports p2sh but it is only because "mystery" is only broadcasting blocks to other pools and thus those pools are relaying them to blockchain.info.  So "mystery" blocks appear to blockchain.info as coming from Deepbit and other pools.

On edit edit: maybe not.  Other miners may be relaying through deepbit. Hard to say if the p2sh blocks shown "from" Deepbit are from mystery or another miner.
You are not right.

This site uses block hashes provided by me, so it's always accurate: http://blockorigin.pfoe.be/

Glad to see you testing p2sh DeepBit.  Was confusing to see blocks w/ p2sh coming from your pool at same time mystery miner started relying them through you (and others).

Interesting mystery. Subscribing.

I wonder where all this hashing power is coming from.

How much hashing power are we talking about?

12.5% of the network. They are getting around 30 blocks a day. So around 1.4Th if the network is running somewhere around 11Th.

Almost 1.8 TH (and growing) if earlier reports in the thread are to be believed...

EDIT - Ninja'd. The only other single entity that has comparable hashing power afaik is ArtForz.

30 blocks/144 blocks a day=.20833333*100=20.83% of the network. At 12.5% for 30 blocks that would = 240 blocks a day.

Bitcoin is about freedom.   The protocol rules so you can mine a block with no transactions yet people decide "it isn't fair" and want to change it.  Some people just can't escape the nanny state mentality ("there should be a rule against that").  Sad. 
While I don't think that ignoring empty blocks will work the way some people hope, that seems like an incredibly broad and childish statement.
"Oh, you think there should be a rule against something that could be considered an exploit? Clearly you're just some pathetic government lackey who HATES FREEDOM!"

You said it yourself: The entire Bitcoin protocol is a series of rules designed to force people to behave.

I still think the most important thing is that they have not figured out how to circumvent the proof of work...  they will eventually include transactions when you can make some btc's from it..  currently it is still mostly block reward!

Why do we know that?
We know that they solve about 30 blocks/day.

For all we know they might have found a semi-analytical/statistical algorithm that just takes a few computers and we calculate their hashing power only by solved blocks. AFAIK there's no conclusive evidence that it takes them 1.4GH/s to solve 30 blocks a day. That's just based on the current difficulty. All we know is that it still takes them at least some work to do it, otherwise they would be faster by now.
