This is a debatable topic, and the cause of some major issues that happened just today.
I am pretty new to the server still, and don't understand the past history of Gaminglight, but from what I saw. if you just be respectful when stating opinions. I think you should be just fine, everyone I have seen that was banned in the past was because they were in one way or another disrespectful. I however think sometimes the line between criticism and insulting is easily misconstrued.
At the end of the day, I feel like this is a place to have fun. If you do not like something in the game, make a suggestion about it and see what people say ^_^. I have seen SMT add in so many suggestions and it's amazing.
Just how I feel...
