Hi. Serious question. I'm new to this forums and new to a few coins I'm looking into, but not new to bitcoin. Any time I make posts or comments, someone always has something really pessimistic or rude or judgmental to say. Just doesn't seem friendly to new people or those who think outside the box. How come? 
Unfortunately, you are right.
It seems that anonymity in the virtual world gives people the courage to do what they otherwise would never do in the real world.
The only way to keep this forum a friendly place are increased activity of admins and banning users who do not comply to the forum.
People are banned for breaking forum rules but being mean or saying something someone doesn't like aren't against the rules and the staff have better things to do than remove posts from people who just disagree or don't get along. It would take a lot of time and effort from them so they don't get involved with users business mostly which is a good thing and that's why scams aren't moderated by staff here either.
