Just because a company operates under several names doesn't mean they are bad news. For example, GM (Chevy, Buick, Saturn, GMC, Oldsmobile, Pontaic, Saab, Hummer). Or Newegg (Newegg, ABSPC, Nutrend). Let's see if thier Reseller Ratings are equally bad (probably)...

In this case, it appears they are starting new companies when the rep of the previous company gets bad, so, they, in fact, do suck. But you can't always assume that.
