Doesn't help that there are tools that tell where S-ranks are without even being close to them, already seeing some notorious players using these tools to quickly reach (and possibly kill) marks they didn't even help spawn. As they don't seem to get banned despite being reported multiple times by different people I guess SE is fine with it.

I feel that S-rank hunting in it's current state has a huge negative effect on the game with some level of cheating the only way to reliably participate and cross-realm travel only made it worse.

Would be nice if there was an area wide message telling when a mark has spawned as well as a 3-5 minute immortality to at least give the people who spawned it a guaranteed kill as well as locals a chance to know it exist, even without using external tools.
