Actually you are all wrong. Bigpoint can see if an account is using a script just by the user profile, However they don't just 'block' any account, Because they must have total proof with the logs off the account etc.. And 95% of times they don't be bothered to check the account logs, They just wait for there special script to detect it. To the 'Ban stage' There is no rules of this. They made no official announcements that the ban stages will not be taking part in the game anymore, So if they were to have done something like that without informing in official forum, they would be liable, It's true that they don't block in top 100 so easy like top 1000's but it's not what you think, They do not block so much players with 'Colonel' rank, Because this is the rank that participates in keeping the ranks in order.. Even though they are crazy this days because of many NPC botters, 2 Stars (Chief Colonels) Will be blocked like top 1000's players. Top 10 users Are checked oftenly.
