I went to your local board, at the bitcoin discussion and all topics were in French there.
Didn't find a single topic in Chinesein this board

Spam is a problem of the forum. Go to the bitcoin discussion board in the main forum. It's 90% spam.
At altcoins discussion it's 100% spam.

Your local board looks ok to me. Everything is in French as it should be. I can't evaluate what they are saying, but I know it's 90% trash as most the forum.

Can you link a board with real problems?

And by doing a topic like this, theymos may be inclined not to help asap...
