I know how you feel OP, it's really annoying seeing a fursuiter post a picture of them shaking their ass or hiding their crotch, and then when you talk to them sexually, they act as if you're a creep and their suit isn't sexual at all
I've even seen them post about how they hate it when randoms dive into their dms with lewd shit... and then a few minutes later post about how they love it when their favourite murrsuiter sent them nudes out of the blue
Here's an interesting fact, loko here sends people unsolicited murrsuit porn to people he wants to fuck, it's his way of introducing himself.
If you go buy a suit and post lewd pics on twitter, you might get a message from him or someone simillar.
This is likely the reason why they they post lewd shit that's not actually nsfw, they want to advertise that they're down to fuck but don't actualyl want to post their dick online
