Sharegod ...... welcome to the twisted ways of the London Stock Exchange, where they have looked after their own for years and years and the PI can just go and shove it !!!
I expect Crest have been requested to disable by the LSE to save embarrasment to there bretherin, the market maker and hence save further embarrasment with regards another shorting scandal.
The AIM market overseen by the toothless FSA who see what goes on underneath the umbrella and does absolutly fuck all about it.
They are all in it together ... just one big happy family going back hundreds of years
