A squatter has taken over a defunct domain at the far end of a link buried somewhere in the 3800 posts you find here. In place of the useful page I saw, you’ll see this stylin’ popover:
The “standard security check” is a nice touch, although you should keep in mind the Dilbert cartoon about unexpected side effects.
The actual URL, which I will not make clickable, includes the domain
ffgetsplendidapps, which tells you just about everything you need to know about what’s going on.
Because they’re squatting, “continue directly to your destination” means being dumped into a Google search after they’ve meddled with your browser & system configuration. Clicking the inconspicuous × in the upper right closes the popover and dumps you into the search, perhaps before doing anything.
I have no good (i.e., automated) way to find broken links and, as far as I know, there is no way to automatically detect domain squatting, so you’re on your own.
Trust, but verify!
