I would like to add another experience of meetup. I joined a hobby group ran by a man.It was a mixed group.I liked this group and nobody was toxic towards me.But later I was told there were these two women in this group who were fighting for the attention of the group leader who was single.He was a nice person and was being really friendly towards me.That is when I was told( warned) about the two contenders already trying to win him over.I was not there to look for a romantic interest.I continued attending because the group was nice overall. But soon enough I didn't want to caught up in triangulation because people started noticing he was being very friendly to me.I might end up getting caught in the s#@t storm of jealousy from these two women. So I stopped going.
