What can be done about PEST sorry GUEST observer who seems to troll a number of threads, considers himself a world expert on all matters and rapidly p*sses everyone off with his huge cut and paste arguments which actually have little to do with the topic?

The subject we were discussing above the line ended up with those of us who know each other* continuing on other sites and by email, to a satisfactory conclusion.

Sadly other people not in that loop may never know the information.

Which sorta defeats the purpose of asking questions and offering answers when a smart-ar*e (who actually knows considerably less than he thinks) butts in and will not go away or at least hush up!

*some of us use our own names, other use pseudonyms - but certainly in the Scottish folk scene we all know or can work out their identities!
