Yes, as we have all told you before:

If there is a known mathematical relationship between the two nonce used (k₁ = k₀ + n OR k₁ = m * k₀) then you can derive the private key from the two signatures.

This is why the k value is picked at random (hopefully from a secure random number generator).

The key phrase here is "known mathematical relationship between the two nonce"

We have shown you the math for this - several times.  You should be able to do the math yourself at this point.

What does the address 1FvUkW8thcqG6HP7gAvAjcR52fR7CYodBx have to do with anything?

Are you really claiming to know that there are two signatures in the block chain using the private key for 1FvUkW8thcqG6HP7gAvAjcR52fR7CYodBx that were constructed with k₁ = 2 * k₀?

How would you know this?
