In an effort to fight spam, Wikipedia now puts the “nofollow†to all external links on all its pages. Wikipedia’s articles rank well among search engines; they also have high Pagerank and some blackhat spammers participating in the “World Search Engine Optimization Championship†tried to exploit this by placing a bogus link which has no reference to the article at all.
I’m not surprised by this move, but it has its own pros as well as cons. Adding “nofollow†attribute to all external links would probable hurt the sentiments of those who regularly contribute to Wikipedia. Philipp Lenssen on Google Blogoscoped writes:
What happens as a consequence, in my opinion, is that Wikipedia gets valuable backlinks from all over the web, in huge quantity, and of huge importance – normal links, not “nofollow†links; this is what makes Wikipedia rank so well – but as of now, they’re not giving any of this back
I would certainly agree with Philipp in this regard. Folks at WikiMedia should work on a better spam prevention technique, like adding “nofollow†attribute to links from a particular domain (not all external links).
Some search engines like WikiSeek depend upon Wikipedia’s external links for the sake for relevancy, now that they have put nofollow attribute to all external links. Will it affect those search engines?

This is good for prevent spamming, however i have very great articles for Turkish people and i would like to have some quality from wiki, but nofollow tag is not good for original content publishers like me. My website is small, but i only publish articles written by me.

I cant believe it. Yesterday i worked 3 hours to get a link to my blog ( http://www.seo.webarticles.dk ) on Wikipedia! That is so unfair! But now people got no reason to post on that site…? Is that a good thing for Wikipedia?

It’s very sad that some bunch of people using black hat technique do such spamming activities. There should be a method devised so as to ban only the spammers and innocent and modest posters like us should be saved from the ill efforts taken by others. But I guess it is a very difficult task to differentiate between the black hat and the white hat guys….

I do not agree with this to. That’s very unfair, wikipedia editors delete all link withc aren’t related with article. However this is very unfair for publishers. What on earth will motivate them?

Yeahh. William - it was not your day. Wiki with it’s resources can filter “black” links with no problems. Maybe it is temporary solution?

I think they must find a better way to prevent spam .
Making nofollow links will hurt publishers.
