June Drop in PartyPoker Numbers

[Sciolist]

Hello,

Does anyone know why Party had a drop in their player numbers in early to mid June? I'm taking this from http://www.pokersitescout.com/ - unfortunately I'm at work so I can't show you the graph I made of it.

Is this when the SNG bug appeared? Is it something I've forgotten? Publicity on gambling bill perhaps? I'll post the graph when I get home if I remember to send myself the spreadsheet.
