It's a like stalking was 15 or 20 years ago and to be honest, until there is such an instance that brings a huge public outcry (like Rebecca Schaeffer in 1989), nothing will be done or can be done by the law.
You may not ever get "anti-trolling" laws...however, it would not surprise me if a high profile civil case related to trolling got people thinking and taking action...
For example, the story that Brad shared where a Jew (I think?) was mailed a box of ashes is the kind of thing that I can potentially see going to court...it wouldn't be the first time that someone sued because of distress and such, and if such a civil suit did occur and awarded the plaintiff amply, I can easily see that affecting society...once you have a precedent, you don't necessarily need "official" things like laws or regulations to get the results you desire....
Put another way, you don't need anti-trolling laws to curb trolling (or at least most of it)...
Let us consider these forums as an example....imagine (if you can) these forums without moderators...so if we have a troll, you can't just ban them or remove their account....so, what would happen? Let's neglect spammers and the like and focus solely on just trolls...
Well, some might argue that the trolls would grow exponentially and the website would be overrun by trolls...but honestly, I don't think that's what would happen to these forums...
Look at this thread...take out all of Jafo's and Frogboy's posts, and you still have a thread with a lot of people very much so against trolling (on the web or otherwise)...the point is that the culture of these forums doesn't depend on the moderators....it's not like Jafo is a one many army standing against all trolls...the majority of people here on these forums don't like trolls either and look at them with disdain....
Monk and PoSmedley didn't need a moderator to get them to speak out against my post "defending" trolling....and if a troll were to come on here and really try to troll this thread, many posters would ignore them...the seasoned posters aren't going to "feed the troll" by getting pissy or responding...at most you might get a few curt posts telling the troll to go elsewhere...in short, the community here does not support trolling, and thus I would be very surprised if trolling proliferated on these forums even if moderators weren't doing their jobs...
I do concede that you would see more short bursts of trolling...but I think the community would "starve them out" so to speak and such trolling would quickly disappear (as in the troll would simply move on)...of course I don't have proof of this, it's just a theory...
However, I can say with certainty that many trolls on the Sins forum (which does not seem to be regulated very much) do in fact "starve" without the need for moderators getting involved...there is a reason why the modding section of the forums hardly ever gets trolled, and that is because the modding community simply does not tolerate it...trolls there are ignored and shunned...put another way, trolling the modders "isn't fun"...
Trolling the MP crowd however works extremely well because they will "entertain" the trolls by responding...put another way, the troll can easily "get a rise" out of the MP crowd...
If the culture of a forum does not make trolling "fun", the trolls will go away...with or without moderators, these forums have a culture that makes them a very poor target for trolling...now I wasn't here when these forums started so it may be that strict moderating made that culture in the first place, but ultimately I see these forums as a prime example of "democracy policing itself"...
More to the point of TBS gamesites having less trolling, those sites simply have more serious cultures that focus on legit strategy discussions, modding, etc....trolls simply starve on those sites because they "audience" just doesn't take the bite...trolls are ignored and the community polices themselves...
I understand that not all trolls can be ignored and that independent of trolling, we need moderators to deal with spammers and such, but most trolls can be easily starved -- it simply takes a strong community that polices itself...
