If you take a look at the recent ban of gambling, you may wonder what's coming up next to be banned or limited. If Lindenlab would be consistent with their intentions, one things really pops up mighty in my mind: prostitution.
Sex and, yes, prostitution, though most people prefer to call themself in an euphemistic kind of way escort and not prostitute, is one of the big driving motions behind Second Life at all. And, yes, like gambling it's prohibited in many countries Second Life is available.
So if Lindenlab is really consistent about establishing a somewhat "cleaner" Second Life this must be next on their agenda: the containment or even shutting down of most prostitution happening in Second Life.
Either that, or as another consequence building up a new strictly, clean, separate corporation grid without this kind of business at all, like the Teen Grid is today. But then again, this would hurt their land sales, since it would depend on how many residents of course would like to visit this clean grid and you got more possible visitors on the main grid than on an own corporation grid. But for strict in house usage such a grid would be a heavy, good asset for Lindenlab to have.
This would of course hurt the in world economy great lengths since most of it is built upon sex, sex, sex, and many people come into Second Life to get laid and many females are working as escorts or dancers at least.
But it's the next logical step in the development of Second Life at all. In my opinion the question is not if it is going to happen at all, but how and when it is going to happen. This is bound to happen sooner or later if Second Life should still appeal to big real world companies. A cleaner grid could mean better land sales to such companies and in the end it's all that counts for Lindenlab. Sales, more sales, more and better income and profit to be alive.
