Why people argue about this

People often assume that stepping over the foul line means they have to throw again if their bag doesn't land in the hole, forgetting that it only counts as a foul if the bag touches or goes past the line. They also misunderstand competitive play where such an error could result in penalties like losing points for that round, unlike casual games where a quick re-do is allowed.

Section 7: Violations/Penalties

Foot fault / stepping over the foul line: The pitched bag does not count and is removed from the board before scoring is tallied for that frame.
Throwing out of turn: If a player accidentally throws before their turn, casual play typically allows a friendly re-do; competitive or tournament play may disallow the bag or require the offending side to forfeit that bag's potential score.
Interference: Touching, moving, or bumping the board, or interfering with an opponent's bag while it is in flight or resting on the board, is not allowed. If interference affects the outcome, the affected bag is typically re-thrown at the group's discretion.
Disputed bag position: If it's unclear whether a bag is touching the ground versus resting only on the board's edge, players should physically check by hand (lifting nearby bags carefully) or use a straightedge/flashlight to look for daylight under the bag. When in doubt, the benefit of the doubt customarily favors ruling the bag "on the board" (1 point) rather than off, unless clearly resting on the ground.
Unsporting conduct: Deliberately distracting an opponent during their throw (shouting, waving, stepping into their sightline) is discouraged; most casual groups adopt a "wait until the bag leaves the hand" courtesy standard before any trash talk resumes.
Board damage or movement: If a board shifts out of position during play (e.g., from wind or a hard-thrown bag), players should reset it to its marked spot before continuing, and any bags thrown while the board was out of position may be re-thrown by mutual agreement.
