I think this thread has run its course.
This is an adult sex-related site, and by using it, yes, you're probably going to be more exposed to x-rated things, than if you choose not to use it. The site has put tools in place for people to manage unwanted communications, should they wish to use them. There is no lush law against sending an x-rated pic to someone via the internal mail, solicited or otherwise, and I can't see that changing. Some don't like it, some do like it and others just don't care. Personally, I think it's fucking weird. As others have said, if you don't open with that in a bar, don't open with that here. But this is a sex site, and it will not even cross some people's minds that this wouldn't be allowed.
However, we will not tolerate harassment under any circumstances. If someone has been asked to stop and doesn't, this will be investigated and acted upon. You may not find out the outcome of this investigation, or you may not agree with it, but that doesn't mean nothing has happened.
But the first line of defence are the block tools available to you, which we ask all people to make use of, as with any other site on the internet. All the mods are members too and this site is meant to be fun. We don't want to start strictly policing every aspect of people's interactions. Yes, it would be nice if it wasn't a thing, however it would be naive to assume human nature is going to change any time soon.
If you report harassment, it will be investigated. Reports are monitored throughout the day by various mods. Discussions are had about any cases that cause concern, and any permanent bans go through admin, so there is an additional layer of scrutiny. All this reporting activity is logged, as are any outcomes.
