another mistake of contest organizers is not publishing table lists for all contest participants.
everything should have been prepared by the organizer for the table of participants. so all participants can find out the order of winners who meet the requirements. if indeed the contest is meant for world cup betting. they should still have all the data.
We had a table for the top 10 race leaders, however none of them had filled the requirements of Twitter to be eligible in the end.

You made a mistake, now you should fix it.
You still should have all the data to create a table of leaders who had filled the requirements on Twitter to be eligible to take part in that contest. (Similar to table of leaders who have not met the conditions on Twitter)
I don't think it is that hard to create such a table, and even if it takes some time, just take it as a lesson for the future.
