I have notice some may be a bit confused on what they think scat is, at least for this group. Please allow me to explain what I think scat is. Scat isn't just a messy diaper, I feel most people of this fetish are fine with messy diapers espically with rps, so I think a group that just wanted that would be too simple and could invite anyone. I think they need to like the mess a lot, like they would rub their butt in it or even go sexual with it. Actually it can go a bit further where they like the torture aspects it can provide, such as dirty diaper facesitting or basically getting the poo out of the diaper and using that in anyway. Of course it can go a lighter direction where they just like how warm it feels and like to see hypermess. I should add in that you don't have to like it in real life, just fictional like rps and drawings or whatever.
Same idea for pee, you could just like that and be invited here too. Hmm maybe I need to add that to the group title... I'm not sure.
