  QAnon is an umbrella conspiracy theory that encompasses a wide spectrum of
people. The COVID-19 pandemic has helped raise the QAnon conspiracy theory to a
wide-spreading movement, especially in the US. Here, we study users' dynamics
on Twitter related to the QAnon movement (i.e., pro-/anti-QAnon and
less-leaning users) in the context of the COVID-19 infodemic and the topics
involved using a simple network-based approach. We found that pro- and
anti-leaning users show different population dynamics and that late
less-leaning users were mostly anti-QAnon. These trends might have been
affected by Twitter's suspension strategies. We also found that QAnon clusters
include many bot users. Furthermore, our results suggest that QAnon continues
to evolve amid the infodemic and does not limit itself to its original idea but
instead extends its reach to create a much larger umbrella conspiracy theory.
The network-based approach in this study is important for nowcasting the
evolution of the QAnon movement.
