Dear admin.
We are confused. Because the thread was suddenly deleted yesterday.

Can you explain why the thread was deleted?
Add child board?


We look forward to hearing back from you.

I don't know what are happening in Japanese local board because i don't know Janpanese. But i think, it's very dangerous, if your local board meets same situation as Vietnamese had been. Bad guys abused Vietnamese local board, Vietnamese threads to spam posts, make non sense posts, so bad, finally, hilariousandco decided to prohibit creating new Vietnamese thread and making posts in Vietnamese. I totally can't understand Japanese, but if this situation, is happening on your local board, you must tell them to stop it. or the consequence will be, you know it.

I usually translate in Japanese forum. I was confused as all translated [ANN] and [Bounty] threads were deleted.
Since there is no announcement in advance, I think that not only Japanese but also ICO organizers who wish to translate English to Japanese are in trouble.

Also, it seems that threads about Japan-based tokens have also been deleted.
Although I am a beginner, I know that what is important to the cryptocurrency is the community.
I think the Bitcointalk admin knows that it is critical thing to delete the community rather than me.

Why is it only Japan?
