People that have no name or an unpronounceable name, yes. If you are literally unable to identify a person (except for disguiser) then it's a simple case of warning them to change it or else get kicked.
As far as a name that is similar to another, I don't get why people can't just figure out to say "It's the guy called _______" rather than "It's bobby" (if there are multiple bobbys) and get everyone confused.
At the very least, such a blanket rule on the issue makes it even more of an issue. As usual, admin discretion on whether a name is interfering with the game should be enough.
I've only ever seen this done for names like the bobby example or for blank names. Admin discretion will solve this.
Well since the suitzoom command provide claims with the perpetrator's name both at the start and end of sentences, it's pretty easy to tell if someone has a fake 'unidentified body' name (e.g. "An unidentified body is a traitor!" may be confusing, but "I'm with An unidentified body" is easy to tell it's just a joke name). As for someone being KoS'd for calling out someone with that type of name...I don't think I've ever seen that ever happen ever. Admin discretion will also solve this anyway.
"This guy" and "That guy" are not words that are a part of the suitzoom function, and therefore cause no issues. As I've already said, those names have only ever caused problems when the entire server decides to jump on the bandwagon, and that is extremely rare. Admin discretion will solve this too.
Except it doesn't. It's just funny to hear people say those kinds of names.
This has always been bannable. Not sure if there was anything covering it though, so this is understandable. Although admin discretion would solve this without the need to ban funnier and non-malicious names.
Also, got to add I am kinda guilty of this. I once got most of the server to change their name to some variation of "Not Octa". I didnt ask them too, they just did it. But it was just for fun. If they are copying someone else's name purposefully to ruin the game, then something should be done about it. But this is such a vague issue I find it would be hard to have a propper rule in place
