I don't know if he's following Voller, but look at his votes:
Day1:
Alen, Salvo, Bezzy, Salvo - there were already 4 votes on Salvo when he placed his vote
Day2:
Voller, Fint, radekas, piotrr, Tomice - voted on Tomice as one of the last voters
Day3:
piotrr, X (wtf?), Preet, Fresh, Preet
Day4:
he waited for someone to start splitting the votes, then voted Ford
Now he immediately picks up Voller's vote on Bezzy.
