They weren't part of his sentencing because a different court entirely was pursuing the hit for hire attempt charge, but because another court in NY got the book thrown at him for running the site, they decided to drop it because it didn't seem necessary anymore.
In hindsight, the prosecution probably wished they didn't do that, since they are said to have had overwhelming evidence and proof, and there is even a Wired article about chat logs pertaining to DPR seeking services, but those are the breaks! If you don't do your due diligence, criminals can be let off on a technicality too!
I haven't looked into the case(s) for years, but prosecutors don't often just drop charges because other charges were found guilty. People get charged even after life sentences have been handed down.

They absolutely do that all the freaking time. Especially when other convictions already result in a long sentence.
Prosecutors have limited bandwidth, and just wasting time adding one more life imprisonment on top of a life imprisonment is not helpful.
Perhaps. I can't think of why they ultimately decided not to move forward with it, but here we are.
