### Contribution Scoring on CF is SHIT

I think the contribution scoring on CodeForces is really messed up. There are no official blogs explaining how it works. Also, the way contribution points increase or decrease really makes no sense. You get +1 contribution point if you get like 5 upvotes and you get a point decreased from your score if just one person downvotes it. Even if someone upvotes it later on and the number of upvotes reaches the same as it was before, the contribution point doesn't go back to where it was. I think a lot of people can relate to this. As I'm writing this blog, I have +5 on a comment and 0 on another comment and yet my score is -1 (The second comment got upvoted and then downvoted and now it's at 0). Can someone explain how the scoring works exactly?

 » 5 years ago, # | ← Rev. 5 →   -21 This is how it SHOULD work, but I know it' s messed up (a moment ago your contribution was -4, it makes no sense at all).
•  » » 2 weeks ago, # ^ |   0 it is still -4
 » 5 years ago, # |   0 There are no official blogs explaining the how it worksThat's because there is no need to know that. This site is for programming and not for gaining useless contribution points
•  » » 4 years ago, # ^ | ← Rev. 2 →   +17 contribution is not useless! It shows how much you can rely on someone's sentence and sometime's for some companies having a better contribution is more important than having a good rating!
 » 5 years ago, # | ← Rev. 3 →   -16 Can someone explain how the scoring works exactly? // code to calculate cf rating #include using namespace std; int main() { long long your_contribution = 0; while(you_are_grey) { your_contribution -= LLONG_MAX; } while(you_are_green) { your_contribution -= 10; } while(you_are_blue) { your_contribution++; } while(you_are_purple) { your_contribution += 10; } while(you_are_orange) { your_contrribution += 40; } while(you_are_red) { your_contribution += 100; } while(you_are_nutella) { your_contribution += LLONG_MAX; } cout << your_contribution<

•  » » 4 years ago, # ^ | ← Rev. 3 →   +8 It completely depends on how others see your comment and blog and how much their contribution is. It has nothing to do with your rating.
 » 5 years ago, # |   +19 I just know votes from high-rated users are weighted higher, which might be the reason.Still, you should NOT care how this function of the site works. Instead, click on "Contests", then click on "Virtual participation", then on "Register for virtual participation".
•  » » 5 years ago, # ^ |   0 it doesn't actually bother me that much, was just curious
•  » » » 5 years ago, # ^ |   +13 Your first sentence seemed very emotionally charged
 » 4 years ago, # |   0 can someone gimme some upvotes, my rating is so low that I think high contribution is my only way to be able to flex with my friends.
•  » » 4 years ago, # ^ |   +8 post something meaningful/useful if you want upvotes. trust me, I learned the hard way.
•  » » » 4 years ago, # ^ |   +57 your contribution may be higher than me, but your rating is not. That what really matters
•  » » » » 4 years ago, # ^ |   0 Your reply is very rude. But at the same time, funny xD.
•  » » » » 4 years ago, # ^ |   0 nice one. I almost didn't have a response...But I do: rating matters in contests, but contrib matters in blogs/comments.
•  » » » » 4 years ago, # ^ |   +2 Also in my defense, I have been getting similar rankings with you lately in Div. 2 contests (788 vs 1132 and I had to leave early after 45 min) so that's what matters too.Btw, since I got roasted so hard, you got an upvote from me :)
•  » » » » 4 years ago, # ^ |   0 I wish I was capable of saying this to someone
•  » » » » » 4 years ago, # ^ | ← Rev. 2 →   -22 SameMost people downvoted me for no reason. They just downvoted me cuz of the huge gap of rating between me and Um_nik. I checked my contribution after that. It didn't drop. That means that most of the downvotes are from greendians and such. Such a shame that most low rated people(and also high rated but at least they weigh depending on the quality of the speech) just mindlessly downvoted me.

 » 4 years ago, # |   -20 Commenting to make a new friend in this community.
•  » » 4 years ago, # ^ |   +6 You lost contribution and still, you have 0 followers(people who friended you) on CF. Rip
•  » » 4 years ago, # ^ |   0 CF upvoting and downvoting is quite odd IMO. people will upvote/downvote something just based on the user who posted it/their rating/their status/they like it or not. Most of the time, people get downvoted for a good reason (some of rotavirus's blogs/comments) but other times (like this) the ratism is quite blatant. Yeah sure, whoever posted this might be on their alt, but still. What if this was someone new to the CF community? They post a comment asking for a friend and get downvoted. I know I'm probably going to get downvoted for this comment, but whatever. Just me going on a rant.
•  » » » 4 years ago, # ^ |   0 What if this was someone new to the CF community? They post a comment asking for a friend and get downvoted.That's one reason downvotes are for. To show ppl that they're not to post dumb comments unrelated to blog comment is in. Ofc this is an alt though and u look dumb ranting abt ratism against an unrated alt.
