I do happen to agree that bluecat is a fucking troll, and doing some shady shit. I do not think that people should be crusifying Scummy though.

Oh, shit. My bad guess I will go into what I dislike about this community, or at least some bits of it.
We'll just not talk about the mod's who like to abuse people with views and opinions that aren't popular, people who dislike the "popular" kinks and fetishes, and work to actively remove reviews that don't fit with what the mods want to be seen on their favorite projects.....
