Welcome to the Q&A Forum

Hi, I have been asked to look at a site where I suspect some questionable SEO work, particularly link building. The site does seem to be performing very poorly in Google since January 2014, although there are no messages in WMT. Using WMT, OPenSiteExplorer, Majestic & NetPeak, I have analysed inbound links and found a group of links which although are listed in WMT, etc appear to 302 redirect to a directory in China (therefore the actual linking domain is not visible). It looks like a crude type of link farm, but I cant understand why they would use 302s not 301s. The domains are not visible due to redirects. Should I request a disavow or ignore? The linking domains are listed below: http://www.basalts.cn/
