Wait a minute here- the entire algorithm is public.  There were NO rule changes.  

The only thing I did was restrict heavy pool users from sending in more than 200 solutions per IP per 10 minutes, which technically didnt change anything yet.
That was on the pool side, to ensure the pool is not overrun by linux hackers.

When I said I raised the Diff, I was referring to the minimum difficulty share the pool hands out, which is not a global rule change, its the pool owners business.

This community has been transparent from the beginning.  I hope everyone can see that.
