The comments I'm seeing seem to be along the lines of....
(From people who don't see/use the sex board regularly)
It's disgusting
It's creeps/perverts/people who are cheating/using it for wank material or hookups or sexting/it's attracting a lot of men
People who are not who they say they are getting off on cheap thrills
It's inappropriate/gross
It's changing what mn is for and who uses it
etc
And
(From people who do use the sex boards)
It's a safe space we like to discuss our issues in a supportive, safe way
You're judging us/you're uptight/it's just sex
We're (probably) consenting adults, and we're within talk guidelines
You're spoiling our area
etc
I don't think either side is 100% right with the lines I've put in bold
However, if I was a creep, cheat, pervert, here to get my rocks off, I'd be attracted to the sex chat boards
And if I was uptight, humourless, prudish, a joy sucker, I'd want to avoid the sex boards
The solution to both these issues?
Hide the fecking board again!
It doesn't seem a difficult solution
