Hi all --

What prevents players from repeatedly "spamming" or "carpet bombing" moves until they work?

For example:

Player 1: I think back about my long talks with my sage mentor.  He mentioned this dungeon a couple of times.
DM: Sounds like Spout Lore to me.
Player 1 (rolls): Nuts, a 4.
DM: You were much too young and distracted by girls to remember anything the old man said about this place.
Player 2: There was an adventurer that would frequent my father's tavern.  He would talk about this place.
DM: Make your Spout Lore roll.
Player 2 (rolls): A 7.
DM: You recall that the adventurer had one hand, speaking often about the traps that were all around this place.
Player 3: Oh, yes -- One Arm Owen!  I remember that guy!  I robbed his house one time.  I snagged a manuscript, seems like he was writing a book about this place.
DM (sighing): Okay, make your Spout Lore roll, too...
Player 3 (rolls): A 10!  Those pages held some useful information, if I remember right...

And so it goes around the table...

What prevents players from each attempting to Spout Lore, Discern Realities, etc. until they're successful?  Seems kind of a cheat to me.
