Unscrupulous users
Your WebUI is used by a person who resorts to one trick. It opens in the browser using a special script from 30 to 100 tabs with WebUI at the same time and starts generation on all tabs. Thus, it can receive a huge number of images without waiting in a queue. This becomes a problem for all other users who have to wait a long time. Could you fix this problem? Such unscrupulous users can be calculated by IP address by adding a ban on mass generation to the program code. By the way, this problem is observed both in the original and in all copies on this site. It feels like there is some kind of anxious person here who can't get enough.
@VladislavMotkov I'm unsure on how to approach this, the code is behind the one who created it (camenduru) and there isn't much to configure or modify
