Just save this as karma.py and run it with Python 3.6 or higher.
import requests
import math
INSTANCE_URL = "https://feddit.de"
TARGET_USER = "ENTER_YOUR_USERNAME_HERE"
LIMIT_PER_PAGE = 50
res = requests.get(f"{INSTANCE_URL}/api/v3/user?username={TARGET_USER}&limit={LIMIT_PER_PAGE}").json()
totalPostScore = 0
totalCommentScore = 0
page = 1
while len(res["posts"])+len(res["comments"]) > 0:
totalPostScore += sum([ x["counts"]["score"] for x in res["posts"] ])
totalCommentScore += sum([ x["counts"]["score"] for x in res["comments"] ])
page += 1
res = requests.get(f"{INSTANCE_URL}/api/v3/user?username={TARGET_USER}&limit={LIMIT_PER_PAGE}&page={page}").json()
print("Post karma: ", totalPostScore)
print("Comment karma: ", totalCommentScore)
print("Total karma: ", totalPostScore+totalCommentScore)
I think, part of the equation might also be that the split between upvotes and downvotes is shown directly. On Reddit, if someone has a comment score of 1, you never know if that’s because nobody cares enough to vote at all, or because there’s a 50:50 split of up- and downvotes.
So if you downvote here, it is instantly visible and not as anonymous.
Also, if a post has a score of -5 on Reddit, you’d assume that everyone hates that post. But here you’d see that actually 50 people upvoted it and 55 downvoted it.
Just for numerical context: Out of my 15 posts only 3 have any downvotes at all. Out of my 332 comments, only 27 have any downvotes.
Compared with 15/15 posts with upvotes and 240/332 comments that have upvotes.
