If you check the profile of this user, you will see s/he has the only one message posted here.
This message, definitely, comes from the only one China IP which has been not blocked earlier.
So, that would mean:
- we can't ban the whole China network from our project, as soon as quite of lots of legal China users are downloading it;
- this user has been posted a definite manual spam message
- it is obvious that this message has been posted manually as it has been passed through ALL of our automated filters
Having just ONE message appearing in a WEEK would mean our protection methods still work.
But it also means, that NOBODY is protected against manual spam, which actually, can not be recognized from any other "human" message without pre-moderating it, or giving other "hard" filters to it...
So I'm sure whatever we have planned, works.
