To clarify:
Someone who appears to be a former GC staff member, with an axe to grind, was making potentially libellous comments. A search for their IP address led to various reported incidents of vandalism on Wikipedia from that IP address, and I conclude that the person in question has a history of troublemaking. We were asked to remove the comments by this person, and we did so.
The comments were made by someone registered as "Train_mad", this person is no longer active on this forum, and if they wish to make libellous comments they should keep the comments to themselves and certainly not post them here. The real identity of "train mad" is known, but no I am not going to publish it here.
People are free to state opinions, or facts, on here. However any potentially libellous comments are subject to be removed if we recieve a reasonable request to do so. If this occurs, the removal of potentially harmful posts may occur without warning. If the post gets many replies before we can act, then it can take a long time to sort out and may result in the topic being closed. Hopefully this won't happen again.
Due to popular demand, I have re-opened the original topic and merged the two together (hopefully fairly seemlessly).
