This is allowed, but take caution

Primarily, we strongly recommend that no one post their real name in full, phone number, work or personal e-mail address, etc. - anything that could allow someone to find you, or your real identity, location, etc.

Posting the country of your birth does not cause much concern, but be aware that enemies of pedophiles and pedophilia frequent this board, so I would be careful not to post enough information that could allow someone to find you.
