Like on social media, users need to subscribe to your channel to get access to your content published by one or more administrators. Earlier, crypto enthusiasts had created a self-described “meme app” dubbed “gm” app wherein users would greet each other with “gm” or “good morning” messages. However, in September 2021, the gm app was down after a hacker reportedly gained access to the user data. Over 33,000 people sent out over 1,000 doxxing messages in the group. Although the administrators tried to delete all of the messages, the posting speed was far too much for them to keep up.
