If you come across any more, please report them! You can report problems with dictionary entries (including AI images) by selecting "Report mistake" in the ︙ menu. And while you're waiting for the report to be answered, you can hide images by selecting "Add picture" and hitting the red down arrow for that image.
If it a post such as the renshuu annual kao coin competition or messages that seem AI, there is a flag bottem to report the message. (And go ahead and use it for spammers as well. I am absolutely allergic to spammers as well as AI stuff. Also allergic to non kid friendly content on kid webs)
