Why is Whistler anonymous?

I'm sure I'll be attacked for running this blog anonymously, so I thought I'd better get my defence in first. I've been a visitor to Greenwich Market since the early 1980s and I still visit the market often and know many of the traders and shopkeepers. I have nothing to worry about, but I have often heard that traders fear reprisals if they speak out openly in defence of themselves and the market. Even being associated with me and my campaign could cause them trouble, so if I remain anonymous any association with me can't be made.
