I agree the transition from "my shop" to "his clients" is highly suspicious. But I actually find something else in that post even more suspect.

When he says "He already said he doesn't even like kids," that is very, very interesting to me, because the poster (whoever it is) is referring back to something Alefantis said to a researcher back in January. The researcher put up a YouTube video about the Pegasus Museum that Alefantis clearly found very alarming; he got into a Twitter DM conversation and phone call with Alefantis, and Alefantis very bluntly threatened his life and the lives of his family. This mirror video covers the whole episode fairly well. In it, Alefantis does three things of special interest:

1. He uses threats of murder in a very casual, practiced way, as if this is far from the first time he has done it.

2. He shows a really shallow understanding of online culture, referring to things he saw on Voat but asking, "What's mods?"

3. He specifically says, "Everything they say about me is true. Except I don't like kids."

This visit to /pol/ has all the same characteristics. It sounds to me like the same guy. Alefantis is not a criminal mastermind, he plunges into interacting with researchers without preparing or thinking things through. He leaves a trail of clues a mile wide. As someone observed in the /pol/ thread, "Protection from officials has made you all sloppy, sloppy, sloppy."

I strongly urge anyone investing time in researching Pizzagate, to sit down and spend an hour or two just absorbing the clues that Alefantis provides in that video, linked above.
