Mario,
Philip would be the one of the top authorities on Chinese swords (Google it)...notice the rest of us can tell you it's a fake...but Philip can give you the details....several members on the forum have been collecting for a long time...and have seen what has come around.
The more recent fakes coming out of China are getting better and better at first glance...but still have such a crazy mix motifs send red flags....like Philip said...things just don't add up.
And also to answer your one question regarding the specific forum:
