Link 7 provides a link to an online advertising company, not a reference to its statement that one is required, or any kind of content on the issue. I strongly feel this is a devious advertising strategy. --‎ 110.174.237.198 (talk)‎, signature added by Jprg1966  ^(talk)

I don't think that's a fair assumption. The editor who added that link is the one who began the article. The link is there for reference. One could argue it doesn't belong there because Wikipedia is not a guidebook, but don't assume it's there for promotion. Also, please sign your comments. -- Jprg1966  ^(talk) 16:28, 11 June 2012 (UTC) reply
