No, you're spouting an Alex Jones-level conspiracy with absopancaking NO CREDIBLE EVIDENCE. Either prove conclusively there is something truly nefarious going on, or STFU. One person reporting not getting their items "on time" does not a pattern make.
Lots of sites use GoDaddy, lots of sites use SquareSpace, lots of sites use Domains By Proxy for anonymization. None of this is particularly suspect. If you really dig into the source code, you can find the person who created the site - and a little interweb sleuthing shows they live in Florida.
The site is linked off uo.com, but don't expect EA to acknowledge it. EA barely acknowledges that it owns UO, in fact most of the CS personnel think they don't.
As my post history will attest, I'll gleefully hold the dev's feet to the fire when they make bad decisions, but this is just getting stupid. Would more transparency/information from Mesanna be nice? Yes, absopancakinglutely. Is it likely to happen? Notsomuch. Her secrets have secrets. *shrugs*
If you're worried about the site, don't buy from it. Nobody is forcing you to buy tacky overpriced tchotchkes.
