Tamade doesn’t sound in anyway like a Chinese username (maybe Japanese phonetically, but that could easily be a coincidence), but I would let them speak for themselves.

Context is pretty much everything; the only Chinese username I can more or less reel off from memory is '基妮真特么老油条... sabibibi', and I may be forgetting parts of it, but certainly there's plenty of swearing.
I doubt you're required to be a British national in order to invest in British pubs.
