I'll go straight to the point.
It's very clear that the sharing boards are not a welcoming place. People are scared to share because they are afraid that they will be judged too harshly.
People like xdem, me and many others sometimes, just shred these people into pieces over 100 lines of code. It's not cool and it's not fun.
If that was the case back in the day when I was starting, i would have been probably bullied out of a career that I really enjoy.
Comments like this are unnecessary, toxic and they help no one: https://maxcheaters.com/topic/223139-mini-trivia-engine/?do=findComment&comment=2684798
Comments like this breed discussions that make people learn how to do things better: https://maxcheaters.com/topic/223520-polymorph-monsters-after-death-spawn-new/?do=findComment&comment=2688607
I think that comments along the lines of "This is trash, go fuck yourself", "WOW this is terrible", "You don't even know how to write code" should NOT be allowed at all, and people should be penalised for saying them.
If you think that something is wrong with the shared code then, IN A POLITE MANNER, you should write in detail what should change, why it should change and how it should be or even provide a solution.
(Also things like what Kara does where he pops out of the blue to say something stupid and ignite an offtopic discussion should also not be allowed but that's a different story)
What we really need is a Code of Conduct like the one stack overflow has to point users on how to help others.
Let's fix this mess, shall we? People should not be afraid to share.
