Telegram's design prioritizes user security and minimal content moderation, making it appealing for communities banned from mainstream platforms, such as conspiracy influencers or far-right movements. We examine the bi-directional behavior of users in a conspiratorial Telegram group chat during the COVID-19 pandemic from 2020-2023. We find that the network structure of this community evolved throughout the pandemic, where the network grew both in the number of active users, as well as in the number of interactions. This increased interconnectivity coincided with surges in planning discussions for associated offline protests.
