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 #575 (Div. 3)?)
The list only contains the contests which have their annoucement URL (which matches /blog/entry/[0-9]*"[^>]*>Announcement[^<]*</a>) on the contest page.
