This leads to nothing... Privacy first, I don't let other people stick their nose at my private assets, period. I use myfxbook mainly as an tool to analyze my trading. Blowing my account or making millions is nobody's business.
Privacy is an irrelevant issue - when you list an account, you are publishing those account details to the world at large, at least those details which you wish to display - letting 'other people stick their nose in your private assets' is the whole point !!
For those who use MFB as a tool for analyzing their own trading, all power to you - in this case it would not be an issue, would it? If someone could see that back in March '09 you had an account called XYZ that was listed, and wanted to know why it's not anymore, you could tell them to mind their own business, its for your own analysis.
The issue I have is with people who list accounts, they get blown through reckless trading, and suddenly you don't see them anymore - a similar concept exists in the hedge fund fund space - it's called survivorship bias.
This would just make MFB much more transparent..... which I am beginning to understand might not be such a good idea in some peoples eyes..
