Building a blogging community or a large online forum is hardly easy, it takes a lot of work, patience, and unfortunately a little bit of weeding.
There will be people with unruly behavior that will cause your best participants to leave and not return.
There is no easy way to solve this problem, but letting people know as you have here of what's expected goes a long way to prevention in the first place.
Thus your team and community builders have their work cut out for them.
You must, occasionally enforce your terms of conditions if you wish to have unity or an meaningful dialogue.
But beware when you start adding rules, which were not there in the beginning to long-standing existing members.
Still, sometimes you have to pull the reigns and do what needs to be done.
The reality is that no matter what you do, there will be hurt feelings.
I've sure seen some very mean spirited things happen online over terminations, or suspensions and on the other side with dictatorship blog networks and forums where the so-called community builders would single out people they disagreed with and rode them until they quit.
Someone famous once said; "Can't we just all get along?" Sometimes I wonder if the answer is "No" because humans like all the sound and fury, it often seems to be innate.
Of course, once everyone understands that, at least we can all laugh about it and smile.
Then cut ties and/or move on if need be.
I can tell you this, I do not envy your job if you are a community builder on one of these sites or the owner of a social blogging network filled with 1000s of bloggers, each with that creative mindset, it's a lot of work.
Please consider this.
