There Is Indeed a Problem with My Forum

My name is Nanze, I am the moderator of an anonymous forum and I am responsible for managing the daily affairs of the forum. One day, I found that there were suddenly a lot of inexplicable green posts in the forum—— [@administrator, Sword Fusangshen is in urgent need of a new owner, are you interested in looking for a job? [The detective agency is open for business and has many members. Orders are welcome. [The Port Mafia Party has settled in, welcome to sign up for consultation/transaction/information] [The Spider Brigade accepts the bounty online! Let's take a look~] [Rebel Ninja is wanted, the list is shown below, and the reward is detailed inside] I found that not only could I not block these IPs, I could only let them remain anonymous. Later. - "Your skills are mediocre, but you can appear in such a dangerous place to deliver high-risk items... Who are you?" - "Thank you for the invitation. I'm just an ordinary courier." Small theater: "Today's business, two fireball scrolls, a batch of armed equipment," Nanze pressed his hat, "precious items... A red king sword?" He crossed out neatly. "This forum does not undertake the delivery business for such dangerous items." [Nanzi Express, the mission must be fulfilled] Demining: 1. The copywriting is in the first person and the main text is in the third person. It is a green post and a nonsense post. 2. All members have single arrows, the protagonist controls the late stage, and the growth history of Nanfeng Express Courier 3. CP hat stand, even if it is decided as a sequel, there is still an emotional scene! Purpose: Grow in love and dreams and become a better version of yourself
