What do people call spamming saves nowadays?
In the past, there were various derogatory terms for people who would abuse the ability to save the current state and keep retrying until non-deterministic decisions went in their way.
What is that called now?
Nowadays it is called Save Scumming, according to the trope wiki. This term comes from the Roguelike community, and different people may use different terms for that.

I still do it on a fairly regular basis for the simple reason I don't have the time to redo large parts of a game!
