No, but there is an addon for that:
Ability to view who voted content to users with permission Supported content: Suggestion threads Question answer posts XFRM rating reviews ONLY FOR XF 2.2!
Threads are created in the forum with the type "voting competition" type and remain with the same type until the thread is moved or type changed.
The results remain. You can only change the start or end time of voting.
No, there is no such thing. We may add this to Who voted add-on in ACP content voting log.
These are the up and down voting with average score display like in Suggestion and Question threads.
Should downvotes just be ignored or completely disabled?
