Is there a "complain" button for guests in joomla?

Question

Joomla

Greetings. There is a message board on joomla and dj-classifieds. The board is simple, without registration, etc. (as intended). Now the question arose - how to make a button to complain about ads without the need for registration? For example, they find ads, see that there is spam or not valid ads, and simply click on the button. Better with a short form (spam, fraud, inappropriate content, etc.), so that later this complaint is sent to the mail of the admin
