of the 29 i see currently registered, i cant connect 13 to anything ive seen/read around here, and (un)fortunately i have photographic memory for numbers/names/faces.
i can tell, right of the bat, which 2 are the most obvious crashers. the two peeps with listed italian location. let me tell you a funny story...most of the freeroll chasers, which are active thruout the forums out there, regularly try to crash country-specific freerolls, which are very popular on stars lately. specifically, there are/have been large prize pool freerolls for italians, danes, swedes, norwegians, british, etc. so these chasers change their listed location on stars from one such event to another.
currently, on saturdays, one large italian event is very popular.
EDIT: TP, btw, as the owner/organizer of the pvt event, u can email and ask stars support to remove the crashers from the tourney. they have started enforcing pvt event rules lately...but only if the organizers/owners themselves ask.
