Google'ing his name (see page 32) leads to a twitter account (bitcoin-related) with a photo. I also found a company owned by Larry S., advertised by "soniq" on another forum. There's a phone number. But I don't know if it is actually soniq.

Maybe JohnK can help? He verified soniq's ID.

Any GB members from Canada? Are there any means to locate a man knowing his (possible) name and city?

When we have his address, we can send a representative to ask soniq personally these questions:

-what happened to OUR dividends
-what happened to OUR hosting refunds
-what happened to OUR mined Namecoin
-what happens next with OUR mining equipment
-why are we being ignored
