It seems slrpnk.net, anubis, and Safari do not play together too well. After each click while browsing on Safari anubis checks my humanity, and then breaks the layout of the site. This happens on mobile as well as on desktop.
I know Safari users, especially mobile, are going to be a pretty small minority, but there are some things that I cannot do in app currently (mlem) and need the mobile web version.
This occasionally happens to me as well, though it corrects itself after waiting a few seconds and refreshing.
IIRC this happens much more rarely on desktop than it does mobile, both using firefox.
