what about the other side of the argument? using thicker leaders ( I use fluoro or leadless leaders) when fishing places with snags to prevent cut offs is surely better than bare line which is much more likely to cut off and leave a fish with a rig in it's mouth?
End of the day it's user error, some people just dont care and will pull for a break straight away instead of exhausting all options before pulling for a break. Personally I do everything I can to retrieve a snagged up fish/rig and hate to pull for a break. I have been out on a little dinghy in the dark to try and retrieve snagged up rigs, face pretty much in the water to reach down far enough. The amount of trees ive climbed to get other peoples lost rigs and leads because they cant be asked. Most wont even ring a bailiff and tell them the situation.
You cant educate the idiots sadly. Just have to avoid fishing places that they do!
