General: huge filesize
Posts that are extremely large, over 30MB.
If you are having metered or slow connection, lower end machine or mobile device, it's adviceable to turn on "Show reduced samples" in user settings, which will limit posts resolution to 800px.
This option does not apply material under animated tag. Flash and GIF material will start automatically downloading the moment you open the post, WebM material will be buffered after pressing play button. Even with huge filesize, animated material usually do not make browser freeze or crash similar to how Superabsurd_res might.
It's also possible to use this tag as blacklisting by itself or combination to avoid issues with metered/slow internet or low end/mobile devices.
