Good point by Hoosier, tend to agree with all the replies here.
This site is free to access and requires unpaid work by the mods to clean it up.
The url does start with the word 'kinky' so 2+2=...!
I'd also add the suggestion that if you're concerned about spam and off topic adult material, ignore any posts within the last 24 hrs and scroll down to those that have been around a day of 2. As the moderator says the site is cleared of spam daily.
Also, and not wishing to offer a barrage of abuse to the original poster, it is usually quite easy to tell what is adult and what is not check the replies a thread has, and any urls the post contains etc.
