He was already pretty infamous in KF before this forum was a thing if my memory serves right, i think he even had a post in the easy to track hall of shame and was infamous as early as 2021 and had been on the farms since early 2019 according to this
effortpost. He was in the farms mostly to post about tumblr/pony related lolcows and onision
One of his first Nolan-isms was him posting in the farms about some discord drama about a prominent brony lolcow, Lilly Peet, saying he had sekrit info but then backtracking because he either didnt get the go to share it, or was lying like a tard
he was made fun off really early because of this retardation, seems like he joined the farms with just the "Nolan" name
It seems like he vomited alot of random images if Aquinas' post was accurate, most of his postings during this time were seemingly deleted by him with no mod warnings indicating that they took action in doing that for him.
Digging into Nolan's profile reveals a post by Aquinas with a bona fide Nolan moment, quite possibly one of the earliest recorded ones that werent posted by him.
Thats it, TL;DR he came to the farms looking for brony drama and wanting to post about his discord "findings", got mocked, and then posted on the Metokur, Vaush, and the Breadtube threads till he went on the vtuber thread for the first time at around May 2021 if im not searching incorrectly
POST , most notably, he didnt livepost much until he found the vtuber thread, his initial exchange was his spergiest moment on the farms until the started posting on the vtuber thread
