How to report another player?

[BOB]

So I'm coming back to discovery after a while and I've started again, been mining with my starflier, then got a rhino...... Now after a day or 2 I have a civilian transport and I'm doing some trade runs between Bretonia and Liberty.

Now today some nope ~Durandal lurking around west point types to me "you die" and blows my ship up.

Needless to say I'm pretty pissed off now.

No Role playing, nothing. Just "you die" pew pew explosion.

I've never tried to report or sanction anyone before. I took a screenshot of his text and me dying, not that that actually proves a damn thing.

I am very keen to pursue this. How does one go about these things?

edit: I should probably add that I am also at fault here, after he killed me, I said to him that he can't kill me without RP in local chat. Then I proceeded to call him a derogatory term for a part of female anatomy. I'm happy to be punished as well.
