Welcome to the Q&A Forum

Hi Sean, If these are just domains they bought that never had any content, there's nothing to worry about here. Lots of brands buy their .net/.co/.etc versions, spelling variations, and any branded/product terms to prevent squatters from moving in. Redirects of any sort are fine in this case. If they're buying companies along with their domains, also don't worry about it. In fact, I'd say use a 301 redirect in those cases. Google does a decent job of understanding formal purchases and looking for official proof, and they're not going to penalize someone who redirects the site of a company they've purchased to their own. Finally, if they're buying domains based on the link profile, i/.e. just for the sake of links, then you need to start worrying. It's less problematic with 302 redirects, but I would recommend against this type of domain buying altogether. Some people use expired domains as a method of indirect link buying. Here's a still-relevant piece from Danny: http://searchengineland.com/do-links-from-expired-domains-count-with-google-17811
