Used to go to a few Nanaplaza.com meetings, 1999-2005 as it turned out I wish I had never heard of them, I avoid all foreigners in person since then. I was extorted by a bar owing advertiser on there, my wife was threatened and followed home from work with attempts made to find her room number, the usual threats about immigration, blacklisting and violence. In those days many knew each other real names, not a good idea. Happily the bar owner was shot dead 2 years ago after gunning down his ex and business partner.
