W.K.T, Sportsmanship is the badge awarded to users when they upvoted 100 answers on questions where an answer of them has a positive score.
I can see some of the users gained this badge without posting 100 answers. How is it possible?
See this user (sorry to point out; it's only as example), who has posted 68 answers and more than 30 answers have not scored any votes.
Even 0 is considered as a positive score, there are only 68 answers, this badge needs 100.
Some of his answers to questions like this, this, and this have only one answer.
If that posts' competitive answers got deleted and this user deleted his 32 upvoted answers, then only it's possible for this badge.
