When a person comments on FT.com they are required to abide by our guidelines or their comment may be removed. It is through these guidelines that we endeavour to keep discussions civil, so that everyone feels that they can have their say. Those who repeatedly fail to follow the guidelines will be banned.

While the majority of bans are permanent, we occasionally issue temporary bans if a commenter agrees to strictly abide by our guidelines in the future.
