[stefaanapers_9006475]

i am playing in server 67
there is a player "Hosein" who score many 800+ in lab in 1 week ago!!!
he score 910 in normal mode last night,895 in easy mode 2 days ago!!!
even is server 1 best record in normal is not 900+!!!
but he is scoring many 800+ in one week!!! near 6 time i think,he score 800+,and many times 700+ i am sure

i agree with this "cheat" post, he is doiing something, so often 800+, now even 900+ in normal

and he is sharing his info with his guildies as they are 3 now that score often over 800 +
