at this amount of time between now and the merge i would hope for teens to have places they can go to without this feels.
You're not the first teen i know who fall victim to this things, you will find a lot of people thinking "the internet world" or very much the SL world belong to us adults.
As far as i remember going back a long time to being online on many games, people felt "uncomfortable" for an unexcused reason just because you are not over 18 and they are so.
Thats what rated places are for really.
What id suggest is trying to either along with friends make places that would feel more secure from those kind of things, the funding might be hard to get but prolly an all time solution.
i dont trust the SL team would find themselfs giving a hand.
