On The Redundancy Of nofollow
Recently I have been considering the very standard feature of
Wordpress that is adding
rel="nofollow"
to all links in comments.
I posted recently how I was
receiving next to no comment spam
in my Akismet spam folder due
it's latest plugin release. This got me thinking about whether
nofollow
is worthwhile any more.
The History
nofollow
was a
Google creation
from early 2005 that was supported by both
MSN
and
Yahoo.
It was designed to stop the search bots from following links that
weren't necessarily endorsed by the owner of the site it was on. It
had a mixed welcome, but was incorporated by many of the major
players in blogging. I wasn't blogging back then, but, as far as I
can see, there weren't many alternatives other than picking through
all your comments and deleting them.
Better Protection
A lot has happened since then, now we have
Akismet,
Spam Karma,
Bad Behaviour and
probably many others that I don't know about. These days you don't
see much spam on blogs, if at all. The spam blockers are doing a
fantastic job, so why do we need this weak
rel="nofollow"
? I check my blog daily,
if something does slip through the nets, I delete it
instantly.
Do The Spammers Even Care?
In early 2005 the idea of stopping the spammers getting any Google juice seemed like a good opportunity to put them off. Did it? Of course not, otherwise we wouldn't all have spam filters on our blogs. Are the spammers aiming to improve their Page Rank? Obviously they wouldn't complain if it were a side product of the process, but what they really want is clicks. Page views, click throughs, traffic, the more people that see the links, whether on a blog, in the moderation section or wherever, the more are likely to click. While the majority of us do not use any old site as a pharmacy, casino, software seller or whatever, if just one or two people make a purchase then the spammers win (and surely someone is, otherwise they really would have given up by now). Think of the return on investment, considering that spamming a million blogs costs next to nothing. Any purchase is a huge win. Maybe they have ads that pay by the page view as well, every click is worth money to these people.
Don't Follow Spam, Don't Follow The Legitimate Commenter
All spam solutions these days attempt to integrate seamlessly with
the host site so as not to spoil the experience for the user (except
CAPTCHAs, which have serious
accessibility issues), but nofollow
takes that benefit of a
relevant link away from a legitimate commenter. In an attempt to
hurt the spammers, all the real, live, human commenters have taken a
hit and this is the crux of the problem with
nofollow
. There are
other problems, but this I think is really where it goes wrong.
We've Beaten Spam, Lose The nofollow
Yes and no. nofollow
with all
it's issues still had some principles about it. No spam defence is
100% effective either, so if something does slip through, taking
nofollow
away awards the spammer a
victory, until you get around to deleting it of course.
Remove nofollow
from Wordpress? I don't think we are ready for this yet. This had
almost made my mind up on the matter, until I read
Dougal's post
and discovered
Kimmo Suominen's dofollow plugin.
The spam filters, my moderation (if you put more than one link in a
post I do get suspicious I'm afraid) and finally checking every
comment that is posted all keep my blog clear of spam. I can't
guarantee that every comment will be caught before being posted, but
I can guarantee that no spam comment is going to last
longer than a couple of days. That is why I have activated the
plugin and why, given a couple of days, any links in comments will
lose the rel="nofollow"
attribute.
There are a range of dofollow plugins available (thanks Weblog Tools Collection), so if you want to join the revolution, you have plenty of choice.
This is one more way to show strength against the spammers. No
longer will relevant links be affected by spam protection, but no
spam will appear either. I really believe we are winning the battle
against comment spam now. They may still spam, but it's not going to
bother me or my readers. Remove
nofollow
from Wordpress? Not yet, but
integrate this plugin and give everyone the choice, that would be a
spirited thing to do.
