As of March 2023, decentralized social media platform Mastodon had over ten million registered users. In November 2022, there were 2.5 million users registered to the online network, an increase of around 300 percent within five months. Additionally, Mastodon, which shares similar micro-blogging features to Twitter, gained roughly 500 thousand users within ten days of Elon Musk's Twitter takeover on October 27th, 2022.

As of February 2025, one quarter of all users of decentralized social media platform Mastodon were aged between 25 and 34 years. One in five users were aged between 18 and 24 years. Mastodon and Bluesky are decentralized social networks where control and data are distributed across multiple independent servers.

EMTD is a specifically crafted dataset of posts on an isolated Mastodon testbed, using dummy Mastodon user account for emulating user posts and information cascades. The dataset consists of 616 posts, with over 100 information cascades, consisting of 3-4 posts from individual users.
