When Sony finally allowed PSN Online ID changes, it mentioned that you could revert to your old ID as long as it didn't "violate the Terms of Service." But what if your existing name runs afoul of the rules? We now know what will happen. If you choose an ID that Sony deems offensive, such as swearing or bigoted language, it'll automatically assign you a temporary alias ("TempXXXX," where the Xes are numbers) and ask you to choose something more civil. Although that sounds harsh, it's much gentler than what Sony did before name changes were an option -- it would outright ban people who chose offending names.
