I sent an email for ban appeals, i really dont know what i did wrong i wrote 30-40 posts in one day
is that frowned apon to be very active in the forum?
It depends on your post quality and your variety. You might be rephrasing the same idea in multiple threads, posting so many in one board a day that the 20 most recent posts on a board is from you, that it's highly annoying and noticeable.
Due to your post quality and spelling problems, I can understand why you are banned.
