It's really simple. Everyone on this site can post whatever they want. That doesn't mean the Owners of the site will allow it to remain. I have had posts removed for whatever reasons and while it might initially annoy me, it isn't my site.
Depending upon the country where you reside, you might also have the right of free speech. In the US you are absolutely allowed to say whatever you want (except "fire" in a theater), you just have to live the consequences or repercussions of what you said. You might have the right to free speech, but that doesn't mean you won't suffer for it.
For sure you are right...To this date here my problem is more with the members behaviour than with the moderators...Some members insults and act like a mob, want to ban people etc...
this is the problem here....
And some fanatic want to import the way of Tweeter here and increase the control... This is the problem....
But remember that this private site is part of society and i dont want this site to imitate tweeter bannishing citizen Trump and bannishing here arbitrarily...
