No one from those who moan, did anything other, than contributing for themselves.
They actually don't care about the community as a whole, truth is that they want one justice for them, and other justice for others. Not one single moaner you can see on this topic, left any legacy behind him, shared ANY knowledge, that wasn't directly benefiting to them.
Point is, moderators are trying to protect those decent members, from trolls and scammers, and because they (scammers) are making new schemes, rules are getting tighter and tighter. BUT, if you're normal person, with common sense, it will not influence you a bit. It's all about respecting others. If you expect someone to respect you, you have to show that first. And not moan, when you get infracted over mindless posting.
It's like moaners (trolls, whatever you want to call them) are getting away from logic, and common sense, when they are typing those posts, being all tough and cocky, while there's no need for that. Because no staff here should take any bullshit that's being thrown at their direction. Whatever changed, yes, it's changed, so WHAT? Does this part really need further explanation? Forum is not a constant, new people are coming, old are going, stuff changes.
We, users, don't setup rules. (though we can contribute with rational suggestions, and arguments)
We like it, we stay, we don't, we move where it fits for us. There's bajillion of places on the internet, or after all, this is webmasters community, build your own forum, make your own rules, and try to deal with it differently from what you see here.
As I said, it all boils down to decency. If you can't write normal post without attacking someone, then don't write it at all, pass it. But most of these cocky members just like to provoke, and then cry, when they get punished. Because, no one wants to take that. Or read.
Get your common sense together, and be useful, if you want useful community, don't expect others to build it for you. Give others example. Lead.
That's the way how you should roll.
