Although a bug might be at fault sometimes, the person who left the mail and comments might have left hubpages or been banned. Anything they did would disappear, I imagine, including the comments, if they were banned. If they just left hubpages, comments might still appear on others' hubs since you do not need to be a member of the site to post comments.

A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
