For her first 100-200k she used to kill noobs with bushes in Chris kill ems and that apparently was considered boosting? She also used to kill people in front of graal city, other then that she would mob PK or go to mod and PK whenever a mob wasn't there! I wouldn't be surprised if her friend alia used her account to PK also but the time they did it in and the amount of pks she has in itself is a huge achievement!
