Firstly, such is the etiquette regarding such things that I am not aware of any other poster on this message board not attributing content that has been copied from another source in such a way and continually. Not only is it respectful to the author concerned it makes it clear as to whether the content is the messageboard posters very own words or not - and which has a bearing as to how others may respond to the post. As TOBW states, the worst scenario is 'passing off' content as one's own.
