Doesn't it make no sense? Why do people say you need 20 points to enter chat to prevent trolls from jumping in? Basically, a troll could just simply ask questions here for infinity and even if you ban them, it takes no more than a few seconds to start again. The system is wired stupidly if you look at it like this.
We require points so members can become reputable in the community.
Trolls don't care about reputation as a "good" person in the community, and they can come by and disrupt what's available to them first then, be it spamming/attacking others in questions, or leading people on with semi-legit questions just to take people for a ride and waste everyone's time.
You need 20 points in chat to prevent trolls.
Why is there such an anti-troll establishment in chat but not in normal question asking? Why not require everyone gives photo ID and their physical address so you can go and kill them if you troll you? Simple.
The needs of the many outweigh the needs of the few.
The needs of the many only outweigh the few because that's what people think is right. Whether it is is up for debate.
The rules are not set in stone. They are variables on the server that can be changed by hitting a few keys. It's not like it's hard. If I felt like hacking the community, I eventually could, but if fools will change it back, it's not worth it. So what do you gain by creating foolish rules to prevent trolls when by the very nature of this site breeds them because any outlet is good enough for a troll, even if just questioning?
In a simpler sense for some, if you can't completely stop trolls, why waste time setting up blocks in the road that makes it harder for them? You can't stop them in the first place. If you want no trolling, don't start a community; communities always have trolls. Trolls are not stopped by points. As stated before, a troll can earn the reputation and then proceed to disrupt and destroy as much as possible right after.
