Uncle Billy was a raid leader with a server around 40-50 people. Notable people in his server were Karm and Polyhedron69, who both were disturbed and mentally scarred by what they witnessed between the activities in the server. Uncle Billy's server was a very morbid server with constant pings and disturbing imagery. While not too much of a mapping raider, he did however had allies of mapping raiders on his server, and orchestrated raids against few mapping servers once in a while. However, as of August 2, his account was suspended and he has not been heard of since.
Uncle Billy was also speculated to be an alt of Sanni, however, this is yet to be confirmed.
