Thank you! +rep for youLet me get this whole situation straight to everyone.
The person that got 'banned' is experiencing what is called a Credit Cap.
Once you reach 192,000 credits then you cannot earn any more credits until the end of the week.
So don't stress about playing Gruntpocalypse, though you'll reach your Credit Cap if you do the method too much.
