WAF is a clan in Battle Run, consisting of only 5 total members. They rarely accept anyone in their clan. If they did, they would restrict it to close friends only.
W.A.F. stands for We are Family.
Note: Anyone besides these 5 aren't actual members since we know all of our real members. Hope this clears up any confusion.
WAF_FoIIoWmE (double upper case "i")
WAF_FolloWmE (double lower case "l"; Leader of WAF clan)
