This might be true if there is existing live mold somewhere in the toilet (for that, monthly tank bleach tablet) but otherwise a lid prevents spores from settling in the first place.
Humidity reduction by ventilation can slow/delay mold but only eradication stops it.

That’s a fair case. We don’t use one of our tubs and every once in a while we have to flush it with water because we get sewer smell. Unused bathroom facilities apparently cause problems.

Make sure you work the valves on toilets, showers, tubs, and faucets as well. They will dry out if you don’t and then you’ll get leaks.

Isn’t the smell just because the airlock dries out?

I think so; that’s why we run the water.
