I think it's about chance and hints. For me, I've met two people into bestiality, both were from different platforms. Had sex with both. One mentioned during a conversation that horse cum tasted like pineapple (however many others on here have said this isn't true), and I asked him if he was into zoophilia, which he was. The other guy I met, we were chatting about accepting others and different kinks, and he mentioned bestiality. I also asked him if he was into it, and on the end he also said yes. I think it depends on how the conversation goes, you're more likely to reach the topic of zoo through sex, or from my experiences. It's chance on who you meet, it is possible to meet others into zoo, just keep looking
