Blog comment spam has been a massive frustration for our users over the
last few months. Although the original release of MonoX blog subsystem
followed the
Google recommendations for preventing comment spam,
the guys behind this obviously lucrative business don't really care
about "nofollow" tags - they are submitting non-relevant comments
agresivelly. On a side note, there are several companies that allow you
to buy spam comments in batches of 100 or 1000, as described
in this article. It's no wonder that some of our
users got more than 20k spam comments submitted in less than six months
to only a dozen blog posts.
This is going to change with the new,
"social networking" release of MonoX later this month. We provide a
pluggable, provider-based architecture that enables users to pick one or
more public antispam services or develop their own solutions.
Akismet and
Defensio are suported
out-of-the-box; if you want to develop your own filter we recommend
starting with the article on
Bayesian spam filter on CodeProject.
You
may choose manual or automatic comment approval modes - in any case, if
the comment is considered to be spam, it will not show in the comment
list without your approval and your resident spammer will have to search
for his next victim somewhere else.
