Yeah, InterfaceLIFT has been down since Feb 15th, and I saw this when searching this morning as well: https://www.reddit.com/r/interfaceLIFT/comments/aui3hf/interfacelift_hacked_according_to_lastpass_sentry/

We may end up removing it as a wallpaper source in DisplayFusion if it's still down by the time we release the next version.

We're leaving it disabled for now, to make sure it's going to be reliable before we add it back in. Previously we were having to disable it every couple of days when it was down
