So if I understand this story correctly, you weren't witholding blocks deliberately you had faulty hardware.

BTCGuild (eleuthria) informed you of this after he noticed what was happening and your hardware was then fixed to work properly

The btc that eligius is witholding is from the period before btcguild when your hardware was faulty.

If this is the case I think he's correct, your hardware would never have solved a block and therefore isn't eligble for pooled rewards.

First of all, your PR is very good at dealing with such "incident", to make this thing clear, I'll past the timeline and post we have:

In 5.16, I post my ticket.
In 5.21, you replied to request signature for my address, I replied.
In 5.23, you found my signature is wrong. after investigate, I found that I add a extra space on somewhere, then I re-sign the text.
Then, a week passed. After I said that if there's no response, I will post it on society. Finally, you announced.
Then I give you some option.
Then you keep slience and post this.

The last shared submitted on these address is in first week of May, and you keep slience, until I warn you twice.

For your " demanding 1164%-APY interest", Let me paste my last post here:

===============
Hi,

This may be the last time I ask for your response.
You need to choose one of these two options in 72 hours, or we'll 'escalate' this case to the whole bitcoin society, and your local law enforcement agencies may also be involved later.

1. Pay all unpaid bitcoin before 6/15.
2. Pay under a installment plan: pay 10% per week, or pay 5% a week, with a extra 5% interest.
===================

Thats all, 5% interest. If you can pay me in 10 week, you can still pay nothing extra!!!

And for my "hacking your site if you dont pay", I post my origional words here:

==================
2. No one wants to risk its money (or hash power) to behave maliciously, under the design of bitcoin protocol, since it will for sure bring negative benefit. If I want to act "maliciously", I can pay just even a small proportion of 200btc to a professional hacker, and I believe he can tear your site for weeks. it may be a much better idea than messing your share system up with legal traffic.
==================

May be my english is poor, But I think you know what "IF" means. I just said that assume that I'm a bad guy and want to break your site, it's a better idea to hire a creaker than risk my power of calculation.

Overall, I think that you cannot prove that I was guilty, and you are innocent mathematically. The only word makes you look like innocent is like "I am the 2nd oldest pool, trust me".
