I was checking the new and unread topics, and found a topic by @CristianAirlines. He deleted it shortly after, however, this account NOBODY has ever heard of unlisted that topic. The name is @discourse_ai_spam, and he’s a staff member that joined on June 4th. Here’s proof:
Yes, it is a bot that flags posts and topics from new members if it detects it to potentially be spam. If the criteria for a post to be spam is fulfilled, the bot will hide the topic and notify moderators to review. Once it has been reviewed, the topic is made public again.
I have added a description to the bot account to provide some clarity on this.
