Why is limelight gaming a company?
Ultimately to allow extra protection in the case of legal issue, or pursuing crimes. I.e ddos attacks are taken much more seriously by police if it is against a business rather than simply a website.
Equally running limelight as a business to an extent allows for better and more realistic expansion likelihood, better protection of our current assets and to be frank, makes us appear more competent than other servers (especially if taken seriously).
