I have a news section of one website that i have, i have allowed unmoderated comments on it to try and help build up the community factor on the website. however this of course could lead to people taking advantage and posting comments to links to websites i don't want to be linking to for SEO purposes. Now i don't want to set all links to nofollow as i don't believe in doing that. For those of you who manage unmoderated comment posting, how do you prevent links to "bad neighbourhoods" getting onto your blog and what classes as a "bad neighbourhood"?
"Bad Neighborhood" usually directs your readers to unsolicited content such as porn, cheap medicines, and anyother spam which would cause more harm than good. For this to take effect, you might need to closely watch the comments and put in a "rel=nofollow" attribute to the links being posted or else you can choose wisely and remove the hyperlinks from your comments.
An unmoderated, dofollow blog is a very bad idea. Unless you're monitoring it 24/7. Moderate it and remove moderation for regular commenters.
The main problem of having it moderated is i couldn't guarentee i could check it every day (i have a very busy schedule). However i have changed it to moderate if they have no previous approved comments. Over the last couple of days i have seen an increase in bad URL's so have put it back to partially moderated.
