I think it’s because handles are so frequently shown in online interactions. AOL chat rooms at one point did allow people named “Dick Cuntpuncher” and so they wanted to clean up a bit as they went mainstream in the early 90s (and thankfully also did stuff like ban rampant child porn and other truly bad things). I think it would be better to just have a sensible reporting mechanism and expect it’s probably easier now with enough trained modes to differentiate Scunthorpe from actual offensive names (although I don’t really care if people name themselves with curse words so I’m not offended).
