There is bound to be an element of inconsistency in forums as people come in at different times and with slightly different approaches and interpretations. We have a general principle of not doing assignments, but that is not to say that there is no way to get around this. I am afraid that this does go with the territory- there are thousands of posters and things will inevitably get a bit messy, and this is only one of a large list of things we have to look out for (spam, copyright, astroturfing, unsuitable content, etc). However, I think that things generally work out, though there will always be exceptions.
