Built two yeast starters using gallon glass jars on stir plates. At some point in the last 8 hours the krausen pushed the lids off. Should I use it or toss it?
Lost lid on yeast starter.

Unless you're preparing starters in a barn with livestock, I'd use it. I switched to open fermentation altogether and never had a sour beer yet.
Your starter is in a container with a 1" opening and it's actively out-gassing (pushing outwards). In addition, the Krausen itself provides a physical barrier. The Krausen usually has a high content of yeast cells acting as perimeter guards, which any intrusive bacteria must survive while penetrating through the barrier to reach your beer underneath.
