No problem. I actually discovered this via an entirely different route, and it can really be frustrating sometimes.
KDE Plasma is so powerful and provides a metric ton of options. However, a lot of them are lying “hidden” like this. Still, kudos to KDE Plasma for having these options be configurable via a GUI, in a more or less logical place.
The Arch Wiki (and possibly other Arch websites, but when I checked I wasn’t able to catch it) uses Anubis (https://anubis.techaro.lol/) to mitigate AI crawlers causing issues on their servers. Anubis works by making your computer do some computations before being let in. For users like you and me, it’d be a minor inconvenience, but for these AI crawlers, it’d cost them a lot of computation as they hit these sites a huge number of times.
Using Anubis is said to be a nuclear option, but as these AI crawlers don’t care about that, sites, especially FOSS ones, started using it.
