I sort of agree with you on this point - the way the software works, or is perhaps configured, makes it all to easy for people to abuse the system in the way that is being discussed in my other thread Forum censorship - The Issue.
I also agree that education can play a big part in this, especially with some strengthened guidelines as well. However, the sad fact is that users do not even comply with the current guidelines.
Take @WT.Sane 's post above as an example:
This is simply a sarcastic remark designed to make make me, as the original poster, feel inferior. It adds nothing to the debate and is completely unnecessary. More importantly it contravenes Jolla’s existing forum guidelines:
Be Agreeable, Even When You Disagree
You may wish to respond to something by disagreeing with it. That’s fine. But remember to criticize ideas, not people . Always provide reasoned counter-arguments that improve the conversation.
Finally, I’m not suggesting that anybody is evil here, but there are categories of community users on the forum who have greater powers to moderate than ‘standard’ users - we’re not all equal in our ability.
So, I believe you are right in that better education, strengthened guidelines, better control (configuration?) over which users can do what would almost certainly help reduce the ability to suppress posts seemingly indiscriminately and therefore the amount of supression that is taking place.
