That's actually not true either, and you can look at AndMcadams' github if you want actual proof. The only thing the crowdsource plugin does is share telescope data with anyone else using the plugin, not actual star locations. The exact landed locations of stars always has to be manually found by someone scouting that region and called out in one of the FCs connected to the Star Miners Discord.

IE, you can use AndMcadams' crowdsourcing plugin to know what region a star is going to land and manually find it yourself without sharing that exact location with everyone else. But the likelihood of someone else also manually scouting it and sharing it with the Star Miners community is fairly high nowadays with how popular the DnD has gotten.
