Old man wilkers is a spammer on Topix Dinosaur Forum. He was first seen on the forum in June 2013. While he tried making on-topic comments, he mostly made unnecessary and irrelevant ones.

He was the subject of ridicule in one of Pinky And Ze Brain's stories, and was viewed as a clown by both trolls and contributors. He went to the Topix Australia Forum during the Australia Forum Crisis, but his posts were overshadowed by those of more major users, such as Coprolite1. He was once again ridiculed on TAF for his poor grammar, bad vocabulary, and inability to make relevant posts.

He persisited in posting into 2014, but was given almost no attention at all. In the first couple of months of 2014, old man wilkers became inactive.
