Rage posting is basically when you get really angry about something, then take it out on the devs for your issue. I can almost guarantee you that people will dislike your rage post, and the devs will probably not see it.
Please don't rage post, because you will probably feel bad about it later, and there's no point. Writing something in all-caps with swears every 2 words doesn't help fix the issue. It just annoys people. You're better off writing something that's easier to read and understand, and something that people will actually want to help you with. Not a lot of people want to help people who get extremely angry because the 70 mods that they tried putting on the server 'wont work,' or the 'devs are a-holes.'
Please, just write something in a civilized and easy-to-read format because it makes everyone else happy and you will probably get more help.
