Besides that, I think the forum should require a specific format when citing an external source(or the forum rules should require users to specify the text he/she copy pasted in the cited link by highlighting the copy pasted text in bold) and should require one to have further discussion besides the copy pasted content in an article in order to prevent others to spam copy pasted post from cited articles.
I will also vouch for an stander formatting so that it get's clear that the contents were cited.
Jet cash and LoyceV's formatting suggestion seems acceptable. Honestly speaking, we would not even need to worry about all these if the members who are citing, would put their own thoughts in the topics.
