I asked Michael Linden one or two nights ago if it was against TOS to sell real world stuff in SL, like, say RL software, RL computers, RL t-shirts, RL real estate, anything.
He said, basically, Linden Labs has a hands-off policy on the content of what people use SL for, so we can do what ever the heck we want in SL.
My reason for asking is because I AM INTERESTED in selling RL stuff in SL. I love the idea of bridging the gap of the worlds.
FYI, these things ...
From: someone
unsolicited or unauthorised advertising, promotional materials, "junk mail," "spam," "chain letters," "pyramid schemes," or any other form of solicitation
... apply in RL scenarios as advertising that "violates your space" such as junk e-mail (or junk IMs, etc). Entering someone's property (or approaching their property) is a form of solicitation. I don't know how many times I have been bumped undesirably into the opposite direction while flying from Point A to Point B... was that Harassment? No .. I flew into someone's space. Same principle with signs. If you don't like the signs, don't look at them. It's YOUR choice... just like it's THEIR choice as to what THEY do with THEIR virtual real estate.
In fact, I think your avatar is butt ugly. I think that violates the TOS as harassment. (Kidding. I don't even know what your avatar looks like.)
Note that your quoted TOS snippet says NOTHING about a distinction between real world and the virtual world of SL. How many billboards do you see advertising some SL service? And does size matter? How many shop stands sitting out in the open contain "click me to buy xyz"?
They are all solicited. You're viewing someone's paid-for real estate usage, their space.
However, I do fully support the idea of client-filtering to whatever extent... For instance, the Mature-rated sims was a great concept that I feel should be extended with a user-enforced "disallow viewing and entering" option.
I guess what I'm trying to say is that the goal should be that one's right to express himself--even ads in one's own space--should not be thwarted, so long as your rights to hide yourself from such things are not thwarted.
