Bunch of multiple accounts slaved together?

One of my friends just starting out in Fantasica followed a trail of funnily named people posting numbers on each others wall. Each of them were named 'exp-(1 2 3 etc.)' I don't think this is against the rules, but check out the ID '96419311' otherwise known as 'Enslaver3' I wonder if there are more enslavers out there? Scrolling to the bottom shows two posts by exp-1 and exp-2 who have 6* leaders.
