User who want earn the hat each must post 8 comments (1 user post 8 comments, not total 8 comments) on a post and ping the OP
This is important: You need 8 comments posted by each user; less than 5 comments will not trigger it.
Each comment must have at least 1 upvote
If the OP also want the hat, he/she need to post 8 comments too, pinging the other user
Question must be edited by user or OP
User who deletes 5 of the upvoted comments will earn the hat
(I’m not sure about the deleting part, but past users all stated that they have deleted some, not all 8 of the upvoted comments)
