As Thirdspace just said the reason is your posts are regarded as spam. If you use Google translate then they will be in very poor broken English and difficult for anyone else to read. I would advise you to stick to the Vietnamese board this time.
Then learn, or get someone who knows English to write posts in your name. Don't write google translated nonsense because you're only making a fool of yourself and will get banned again and again.
And there's no Vietnamese board, that's why he started spamming his gibberish in English sections.
