I wasn't around back when hunts were first released, but I heard there was a rather persistent issue with people using some manner of program to locate S ranks the instant they spawned and get to them before anyone else.

I hadn't really noticed this being a thing on Cactaur up until about a month ago, where a whole mess of strangers started showing up at S ranks my LS spawns, despite us not giving any in-game indication of one being present by creating a PF or calling it in a different linkshell (I suspect somebody in the LS is secretly using the program, which supposedly will automatically inform anyone else who's using the thing of when a hunt spawns...). There's also been people immediately (Like, within seconds of the thing spawning) linking the location of S rank spawns despite them not even being in the zone.

There's always been people using something to know when a S rank spawns if they're present in the zone, but not where.

It's getting rather annoying, particularly because some of these individuals spend most of their time botting and only stop when they're alerted to a S rank spawn.
