There is an upvoting window on SportsTalkSocial. It is for 4 days. If you convert it into hours, it is 96 hours. So if you upvote any post or comment that is older than 4 days or 96 hours, it will have 0 SPORTS.
Are you serious? I never knew this. 4 days window?
You ran a contest about staking SPORTS. Have you ever checked whether they actually got SPORTS tokens from your upvote?
Frankly speaking, you are the one whom I informed about it by commenting on your post and also tagged your main and sports curation accounts to make sure you get the information.
