`  ==Commercial links== Nelson, I see you are doing some good work identifying spammy links. It's a subject that I keep coming across on small village and town articles. Generally I leave links about sports clubs, schools, community centres, churches and ``local websites``. But there are gray areas and the plethora of links to individual shops and pubs and other commercial businesses I remove. Do we need some sort of formal guidelines about this? A Golf course is an amenity in a way a shop isn't - but where to draw the lines?   `
