I think most fair minded individuals only give the odd thumbs down, I may have given you one or two in the past myself but, it isn't personal, It's just that I don't agree with a certain post.
If you do get a huge amount of thumbs down it's invariably because some crank is getting his jollies...
Nah you won't flounce, not in your nature. You are more liable to a rush of blood and an Expletive Code Violation #1 in the manner of the Noel Edmonds incident.
That's reasonably fair. I tend to thumb up about 10x more than I do a thumbs down, however, I recently started receiving several thumbs down from the same person for no apparent reason so I track down his posts and give him some back, for no reason.
