Findit should provide guides for sheriffs to confirm correct reverts. 

Possible changes:
1. In description, tells Sheriffs to reply the comment saying 'Confirmed'
2. Add a button/radio button on culprit page so that sheriffs can click on the button to confirm
3. Change links in culprit page from build urls to analysis urls, so that sheriffs can go to the analysis to check if the culprit is right or wrong (less preferable)
