The forum is full with non-sense, off-topic and spam and no one seems to care about it.
All the sections are spammed with off-topic posts, topics that not belong to their sub-category and just everything not make sense.
If you guys do not know how to moderate a forum, take a look at Sythe, Powerbot, MMORPG and forums that let their Moderators to take actions.
The best option for you at this point is to stop blabbering and leave this forum if you don't like how this forum is moderated. You can turn into a troll in an instant and start going against the grain when you don't stop blabbering and maybe you won't get any more tolerance and the neutral tag will immediately turn red.
There's nothing wrong with complaining and questioning how this forum is moderated. But be aware that the trust system you are complaining about is currently not moderated so anyone can leave positive, neutral and negative tag on your profile for whatever reason they want. But I believe that no one will touch you for no reason, you should be able to think positively about this.
