I wanted to find some rounds with high upvotes for virtual participating, so I wrote a Python program to get this and shared it to the community. Hope it can be helpful.

For more information and the full list, please visit the Github Repo.

Suggestions are welcomed. (e.g. How to get the announcement URL if it's not on the contest page instead of doing it manually, like Codeforces Round #379 (Div. 2)?)

The list only contains the contests which have their annoucement URL (which matches /blog/entry/[0-9]*"[^>]*>Announcement[^<]*</a>) on the contest page.

UPD: The most upvoted round in each year:

tourist taking both first and second place... sounds like Google Code Jam on steroids.

Is there a possibility of creating a list of least upvoted (most downvoted) rounds? That would be fun to see and try as well.

      I found some meaningless "contest title" in contest.csv,

      such as in line 1050, 647 妥快抒扶抉抗批忌抉抗 2016 — 妍戒扶忘抗抉技我找快抖抆扶抑抄 妓忘批扶忱 2 11

      so what is it?

Project idea: plot the round upvotes with respect to the date of the round, and try to calculate "corrected" round scores that account for the fact that Codeforces has grown a lot (i.e. in the current list, newer contests have more upvotes because there are more members now).

    Now you can see the start time of each contest in the chart.

Create a list of the most upvoted editorials, and the less upvoted contests.

    You can either read the post or the comments carefully to get the least upvoted contests.

    Editorials list is worthy of consideration.

I was wondering why was I notified by this blog entry, until reading the en7 version :D turns out my rounds so far are considerably good somehow (not yet enough to reach top 10).

Also, nicely done with the API and all the scripts. ;)

P/s: Currently thinking of listing contests by comment counts, but the information given by the number of comments in an announcement/editorial is somewhat ambiguous.

    I mistakenly counted a div.1 + div.2 round / a round with the mirror and the offcial one as multiple rounds. When I fixed it, I forgot to sort it again, and I posted it with the wrong order lol.

    looking to the downvotes, it seems is not real, but maybe integer?
