PGA Tour Players Not Marking Balls when In Position to Assist Another Player, #Backstopping

[colin007]

Little bit of backstopping with Lexi Thompson and Pat Tavatanakit today on hole 7

[DeadMan]

Another example:

Pretty bad! Mark your damn ball.

Seemingly a kind thing to do, but you're cheating the rest of the field.

Yeah that's a bad look

What happens if backstopping like that is happening on a green that is close by another hole, and a competitor on that other hole looks over, sees what's happening, and yells out for the player to mark their ball in the spirit of fair competition?

They're allowed to. See 15.3a.
