Spam messages in Chinese from the Community

Hi Lennert,

I don't know if it's only me, but for the past couple of days I've been getting spam messages in Chinese from the Community. The spammer seems to be changing user names and sends multiple messages, one after the other, resulting in dozens of emails cluttering my inbox. Of course I don't want to block emails coming from the Community, and I haven't been able to successfully block these specific messages.

I don't know Chinese, but an automated translation says that it's something offering forged university degrees or something like that. Can something be done about this, please?
