Proverbs 10: 19 When words are many, sin is not absent,
but he who holds his tongue is wise.
I reckon since the forums has mostly 'words' and 'talking', and is used by most folks who are just passing time, it's the perfect breeding ground for bickering and the sin of anger. Maybe if folks find themselves on here getting to the point they're bickering and fighting, it's a sign they aren't engaging in something productive and are instead engaged in 'idle activity'. So instead of continuing in the idle activity of the forums, they should go find something productive to do.....
James 4: 1What causes fights and quarrels among you?
Don't they come from your desires that battle within you? 2You want something but don't get it. You kill and covet, but you cannot have what you want. You quarrel and fight. You do not have, because you do not ask God. 3When you ask, you do not receive, because you ask with wrong motives, that you may spend what you get on your pleasures.
Galatians 5: 14The entire law is summed up in a single command: "Love your neighbor as yourself."[

15If you keep on biting and devouring each other, watch out or you will be destroyed by each other.
And a BIG yikes verse here...
James 4: 11Brothers, do not slander one another. Anyone who speaks against his brother or judges him speaks against the law and judges it. When you judge the law, you are not keeping it, but sitting in judgment on it. 12There is only one Lawgiver and Judge, the one who is able to save and destroy. But you—who are you to judge your neighbor?
