Go to your account settings. Go to the browsing section. Go to the tags section. Beneath the box where you type in tags there's a checkbox to mute AI art. You can also add any tags you want muted there as well, not necessarily AI related tags but anything. You can also go to the home page and click the telescope in the left sidebar. This brings up the topics page and from there choose "all topics". Any topic you want to mute click it and a 3 dot menu will be appear in the top right corner of that page. Click the 3 dots to open the menu and select "mute topic" for each topic you don't want to see. Log off DA and back on for the change to take effect, also give the changes a couple of days to take full effect.
