Anyone know how they do it? Skipping SB on party

[SoBeDude]

I've been sitting here watching this guy names Zkayl at my table skip the small blind every round.

He posts the big blind, sits out for the small, and when he un-sits out after the button passes, he gets hands behind the button without posting.

Party support said they were aware of the situation and were working to fix it. which means nothing to me.

Anyone know how these guys are doing it?
