The consensus seems to be this is a situation where ‘competition’ is in conflict with ‘sportsmanship’ or building friendly environments.
The repeated thing is people do it out of desire to HELP… but at the very competitive moments, it’s a detriment because of the material impact.
How about instead of treating it as some strict rules violation (that is entirely difficult to enforce and scope), why not instead coach it to players as a matter of sportsmanship? Coach that we want each person to compete on their own without external aids… and while we all hate to see someone make an unavoidable mistake, this is an example where outside things can make material impacts that affect OTHER people.
You’re going to have more success convincing people of why the behavior can have a negative impact and attract followers with honey… than you are with trying to outlaw behavior by mandate that everyone can shoot holes through over and over.
Let’s preach what we should all be doing - instead of trying to ban behavior we can’t stop. Discourage it, not try to outlaw it.
Just a thought…
