The best thing would be to get posting though ;)

It looks on r/soccer for any post with the media flair. There's no goal highlight flair unfortunately so there are filters to remove images, gifs, youtube, v.redd.it and posts without numbers in the title. Some non goal vids will slip through (and some missed penalties/sendings off could be missed with the numbers filter).

Worth saying that r/soccer looks the same as here with goal vids everywhere when Europe is asleep. They maybe had one or two posts in between. It's the same on a Saturday afternoon/busy midweek night. I could try and filter out some posts/teams until the sub grows a bit but not sure how.

I don't understand a single line of the python script fwiw. This is all just me asking bing chat how to do it and keeping my fingers crossed that it works.

Edit: One option could be that between roughly 11pm - 10am in Europe (~6pm - 5am EST), a megathread is created and goals are posted there as individual comments instead. This way goals on non European continents aren't completely ignored. Still negatives attached to that option though. Most of this sub will probably be North American and happy to see all the goals posted from the Americas.

It would risk to become very eurocentric if we would say just the top 5 euro leagues or something, and if we were to include South America it kinda wouldn't solve the problem. You could make a delay to goals being posted to when they reach a certain karma threshold, but then there would be a delay to highlights posted so yeah
