Are you sick and tired of the 13-year old vocabulary? How about fanboys and fangirls that think their band is the best in the world, no matter what others' say? Or maybe you just want to brush up on some do's and don't's on commenting and posting on sites such as YouTube and Ultimate Guitar?
Here are some really general and basic rules to keep you from getting those +20 downvotes or dislikes.
1. Don't act like a 13 year old
Calling someone 13 is an insult because of this very reason. If you get butthurt over every little comment that might offend you a bit, then you'll end up overreacting and you'll look like more of a child. Don't reply with vocabulary like "you suck" or "your momma didn't think I was 13," because it proves that you don't belong in the comments.
Even if you aren't 13, you can still sound like one, so be careful.
2. Don't rely on swear words
F*cking B**ches these days just don't F***ing understand that swearing ISN'T COOL! Swearing can help bring emotion across, but don't rely on swear words. Flipping someone off just proves that you have nothing better to say. It's really pathetic to the eyes of others. Constant swearing and profanities will get you downvotes no matter what.
3. Don't mix up opinion and fact!
This is one of the MOST overlooked mistake that people make when commenting. Opinion is something you have, and may not share with everyone else. Fact is something that no matter what will never change, no matter what your opinion is. Let's do a fact or opinion exercise.
The band Queen has a well known song by the name of "Bohemian Rhapsody": Fact
"Bohemian Rhapsody" is the best song in the world: Opinion
This article is really good: Opinion
So don't start yelling at each other if someone says that they don't like Guns N' Roses, and don't go around saying that other bands are bad - Rather, say that you don't like their music instead.
4. Don't reply to the top comment just to have your comment on top
This is the EASIEST way to get downvotes. It's fine to reply to a comment if you have something to say about it, but if it's not even close to being related, it gets annoying and shows that you're an attention seeker. Let your ego slip and have the bottom comment, because everyone has it at one point.
5. Don't blatantly insult others!
"You're a f*gg*t" and other insults can actually damage a person's emotional state of mind. You don't want to be the cause of someone's depression or suicide, right?
Alright it won't go that far, but still, it's just ignorant and stupid to insult others out of the blue, especially if its something noted above (such as someone liking a certain band, or having their own opinion). Insults are something you'd say online but not in person. If you can't say it to my face, don't say it to my Facebook, right? Well, in this case, don't reply to my comment with hate.
Also, trolling is only fun for the troller, so if you like trolling, know that you're doing it for yourself and that everyone else is getting sick and tired of you're stupid jokes. Unless it's a really good troll, then by all means, go for it. Use your discretion wisely, though.
That's about it, I hope you all have either learned something new or have refreshed your memory of general ethics online.
