They get rather upset if you run off with there clothes .

Yup hehehe.

they were my first "wtf" moment in Skyrim

Yeah I was a bit perplexed by them as I had assumed the hot springs to be caustic which would explain why not much grows there. Then I stumble across some hunters taking a bath so there obviously not caustic. I had hoped that by now they would of forgiven me for stealing there clothes but every time I go past they want a fight lol.
