ok please i need help! there is another player posing as me ! what should i do!?!?

ignore him and hope he gets bored enough to go mess with some other person.

In reallife or on SEN? or b-net?

If Reallife -> Ignore or kick his fucking ass
SEN -> change password
b-net -> only way would be name-spoofer... so /ignore only works with the account name, and not with the displayed....
find out his real account and ignore it (but: you'll see his messages ingame anyway...)

btw: you've got -170 minerals.. omg... did you lost so many by deleted posts?? harhar!

WTF are minerals

it's like score on SEN
you get em by posting... more letters = more minerals
with 20 minerals you can play 50/50 Raffle and/or magic boxes
there is a store where you can enable many cool features
you loose minerals when posts get deleted by moderators, so be carefull WHAT you are saying....
don't spam and post useless informations!

you start with -150 so you posted many shit, right? xD
