Is your proposal related to a problem?

Controversial sort is sometimes too similar to top sort.

Example:

https://lemmy.ca/u/dullbananas?page=1&sort=Controversial&view=Overview

This post should be closer to the top: https://lemmy.ca/post/23418411

Completely ignoring the vote count would also be bad because it would cause a lot of stuff to go to the top by having an insignificant amount of downvotes.

Describe the solution you'd like.

Replace (upvotes + downvotes) with least(upvotes + downvotes, 10)

Describe alternatives you've considered.

Use logarithmic scale, just like hot sort

Additional context

Here's the controversy_rank function.

Which is basically (upvotes + downvotes) / (upvotes / downvotes)

Some discussion of that function is here: #2515 , and reddits algo, which is what ours matches, is here.

The fact that it takes the magnitude of upvotes + downvotes, tells me that it intentionally biases popular posts no matter what.

Reddit algorithm appears to use exponent instead of multiplication

[dessalines]

Ah ** means exp. Should be an easy fix then, just changing that function.
