@Kamil118 Thank you for posting this. Like some other people, I usually hate these kind of SNS campaigns but I don't want to miss the Matoi stamp so it looks like I have to join this campaign. Your spreadsheet was very helpful!
@YagyuChan The campaigns are basically the same, but the presentations are a bit different. JP has a dedicated news post for this campaign which they update the count every day, even on weekends. Probably they have the update automated.
More importantly, this post has links to all the eligible tweets for this campaign, so its easy for interested people to join this campaign.
Other minor differences include JP needs more retweet counts (15,000 for Matoi stamp, 25,000 for full SG reward) or JP doesn't have Facebook part, but I think these are rather minor points.
