So, I get there are people here talking about plugs. But, there are other reasons for 18+ events or groups. Even without that in which should not be said.. most adult roleplayers do not want to RP with minors. And I am not even talking the 'e' type. I am talking in general due to graphic language, graphic descriptions, and mature themes. Or even those who are just purely into slice of life often don't even want to RP with anyone who is a minor for their own safety and comfort. While the game itself may be 13+, I personally do not like being around children and I mean that as a whole. Even if I am not roleplaying and I am just joining a FC to have fun, if that FC is not 18+ only, I will not join. I do not want to have to curate my language or what I talk about to make sure that it is appropriate for all minors so instead I curate my spaces to be 18+.
