Shortly after William Lin Fan Club was founded ( https://codeforces.com/ratings/organization/20327 ), substantial improvements of mutiple members of the clubs have been noticed

• dorijanlendvaj, getting +198 by plaincg 4th in Codeforces Round #594 (Div. 1)

• gamegame, getting +152 by placing 6th in Codeforces Round #586 (Div. 1 + Div. 2)

• nikolapesic2802, getting 2 consecutive +101 by placing 44th in Codeforces Round #588 (Div. 1) and 45th Codeforces Global Round 5
