Everyday until you like it:
You know when you spew this toxic shit around, it *surprisingly* doesn't actually help anything. It actually makes the situation worse. Providing constructive and positive posts would go a long way. Remember, monkey see monkey do, when you do something, odds are someone else will follow suite. So when you shit all over your nest, the next person will probably shit all over it too. But when you do something constructive and help the general, the next person will probably want to help out as well.
This is a self fulfilling cycle.
If you want a better general, it starts with (YOU).
When someone else does something shitty, you have to resist fighting fire with fire, it's tempting I know but it goes no where. You have to instead point out they are being unreasonable and provide a constructive alternative to their behavior - the second part is the most important part, providing guidance and structure for them to improve on, anyone can be a critic but providing good and quality information for that criticism can have a profound effect.
Remember, change starts with (YOU).
Don't be lazy and hope some single amazing person will materialize out of nothing and will come and fix everything magically. It won't happen, to fix a community, you have to work like a community.
I'm not asking you to turn into some gay reddit hug box. I'm not asking you to pretend to be something you're not. I'm just asking that before you post, ask yourself a question. Does this help anyone? Is this a constructive post? Am I doing my part in the community? If you answered no to anyone of those you probably should revise your post or course of action.
Remember, /mcg/ is a community. It only works if ALL of us are working together. No lone actors, everyone. Think, and stay positive.
Last thread was a good example of when the shitposting goes too far.
