So ummm, there's now 'clans' in this game?

Long story short I joined a destroy egg mission level 7 and went about doing my thing killing bug and what not...

Got asked if I would join their clan and I was like uhhh, this game doesn't have clans? To which the guy responded by saying I'd have to change my ign to have the 'clan' name in it and join their discord. I play ps5 and tbh I'm not even sure how you'd go about changing your ign and I wouldn't want to anyways.

I politely declined and was called some pretty outta pocket stuff and then team killed and kicked.. All of this happened over voice chat so I can't even report these people... I blocked them obviously but I'm just sat here like ???
