As stated above, Closinator is a chatbot, which aims to eliminate low-quality posts across Stack Overflow. Using certain algorithms, it reports posts to the dedicated chatroom, and users can give feedback as to whether the post is low-quality or not. To participate, a basic knowledge of how Stack Overflow moderation works is needed.
First and foremost, see the definition of low-quality post before reading how to give feedback. This is necessary. Aditionally, one must create an account with Closinator. See Create an account for more details on that.
Giving feedback does not require any privileges (other than an account), and you are free to give feedback at any time. However, if you see any user abusing the feedback system, their account will be destroyed by anyone with the proper privileges.
