SoZardoz, c'mon, you're not going to win any debates on this with the SDF--yes, you're correct in your assessment, but their fanboyism makes them blind to the truth of the matter. This is something that is impacting all Games as Service/Online platforms, and until the rights of customers are respected and provided for by the governments in question, all companies--Sony, Microsoft, EA, Valve--will be able to restrict your access at-will and not have to provide reasons for that restriction.
Which part of Sony's EULA defines what is and is not "severe behavior"? I don't see anything that defines that term specifically. While you and I would understand that swearing (for the most part) wouldn't be severe behavior, if it isn't clearly defined in the EULA, then Sony can define it however they damn well please, whenever they damn well please.
