The trouble is just volume and time, even just reading through the description and “proof it works” would take a few minutes, and if you’re getting 10s of these a day it can easily eat up time to find the ones worth reviewing. (and these volunteers are working in their free time after a normal work day, so wasting 15 or 30 minutes out of the volunteers one or two hours of work is throwing away a lot of time.
Plus, when volunteering is annoying the volunteers stop showing up which kills projects

Part of the book is that everything is slower, it took them weeks to get to the planet from where they met, and Rocky had already spent time retro fitting graces ship to let him live there. (they did not go to the planet with the intention of sampling it, they were just going to sample the line and orbit the planet as an easy way to get close to the line)
It’s been a long time since I read the book, but I think they considered the danger relatively low for the ship with their plan to stay high up and were more focused on “maybe we’ll lose the bucket risks” and didn’t want to go back to rocky ship until they were done because travel time and stuff.
