Well, it appears that Google's Lively does not allow sexual content of any kind.
"Our community standards prohibit sexually explicit images and rooms intended for sexual activity, even if virtual. When we become aware of 'sex rooms' that violate or Terms of Service, we'll work to remove them."
No sex chat at all. Period.
"We don't allow nudity, graphic sex acts, or sexually explicit material. This includes making sexual advances toward other users."
You can't even flirt with someone - that would be "making sexual advances." There goes the breast cancer education photos as well - that would be nudity. This makes "the nipple controversy" at SL5B seem downright trivial.
"When browsing or searching for rooms, some Lively citizens come upon these rooms as the top results, which can erode their Lively experience...Lively is intended to be a place for Lively citizens to connect with each other and express themselves freely and in a safe environment," Google said.
You can express yourself freely, as long as you adhere to Google's Puritanical sense of morality and their sense of "free". Free as in you cannot create your own content and you cannot express yourself without fear of the "sex police" finding fault with what you said.
What does that leave?
"Hey, nice weather we're having. What about those Mets?"
"Let me show you this *awesome* hat I got!"
To which everyone takes out and wears *the exact same hat*.
Zero differentiation on appearance, on action, on conversation.
Oh, did I mention that it's slower than SecondLife?
I think I'll stay with SecondLife where I can have all the sex, drugs, and rock and roll I desire. Even if I'm not allowed to show a nipple...
