How is Activity Ranked on Hacktivity?

Activities on each page are ranked differently.

On the Popular page, activities are ranked by calculating the number of upvotes divided by (a power of the time since they were last updated on Hacktivity). The vote is weighted slightly more if it comes from a hacker with high Signal. Additionally, each activity gets an initial boost if it is resolved and/or receives an above average bounty.

On the New page, activities are ordered chronologically with the latest activity being listed on top. A previously appeared vulnerability goes back to the top when there is new activity on the report.
