According to a Twitter audit site, around 523 of the followers are 'fake' by their metrics.He follows 6k+ people. I just took a quick glance and there's some obvious overlap between who Wes follows and who follows Wes. The ones I clicked on also had tons of followers but nobody really paying attention to their tweets.
Seems like Wesley has picked up followers from all his different extremist soapboxing and sperging, which he does plenty of since he doesn't seem to have had a job in years. Taking a scroll through some of them, I'm seeing BlackLivesMatter/Ferguson/Trayvon, tranny fetishists, SJWs, infosec/Anonymous, shit loads of tranny rat king action, video gamers, sex workers/cam whores, feminists, leftists, LGBT, reddit, pro- and anti-Gamergate, Wiccans, Eve Online, anarchists, bronies, wikis/Wikipedia, Islamic Content and pro-Palestine, Brianna Wu, and, disturbingly, accounts claiming to sell or trade used panties.
