Is Jason Boyko related to all of these sites?

I think those are probably all just WHOIS-guard addresses, so I don't think you should assume he is running all of those sites solely from the WHOIS address. The more likely story is that all of those sites are using the same domain registrar, or that the domain registrars for all of those domains are using the same WHOIS guard.
