I think it's due to responses from Alex "crazygerman" Byron accusing HansanSystems for spamming in his forums and taking up user name that makes him look like he was link to that site itself some how. Alex "crazygerman" Byron seemed to have called HansanSystem to complaint/confront them about the spamming from their IP address and wanted them to stop.
There are similar accusations going on in StorageReviews forums accusing him of spamming and collecting email addresses of members. Some claims that they received spamms from "
www.hansansystems.com" and that this individual keeps openning up threads to promote the cases his company sells.
I'm neutral in all this but that seems to be the "growing" resentments.
