My server that I run has bluemap installed and when I am not in spectator while vanish, I can get shown on the map. I was wondering if there is anything that you could do to add support to those mods to prevent vanished players to not be seen on there. Thank you.

I am currently using the mod on 1.21.1-v1.1.1.8 NeoForge.

Hello, sorry for not getting back to you earlier!
Since I don't have Bluemap set up, are you able to test for me whether invisible players get shown on the map? If not, then I can use that to add compatibility.

Sure that's fine! Be aware that it will take a while for me to test it. Thank you!
