    Drupal is a popular blog format among the SEO community as it is usually very forgiving with regard to adding link-heavy comments.

    However, if you regularly comment with Drupal, you will have been frustrated with this message numerous times:

    "Your submission has triggered the installed spam filter and will not be accepted"

    Wrong - it will be accepted. You might have to change your submission, though.

    The drupal spam filter is a bayesian filter, meaning it looks for signals and attemps to calculate a probability for a comment being spam. It's able to learn, but only on a single site basis. It is not anywhere near as advanced as akismet.

    If you get the message, try these tactics:

    1. Change your link and anchor to something less commercial-sounding.

    2. Increase the length of your comment. The filter will be triggered if 20% or more of the text is html code.

    3. Change the location of your link by putting it in the middle of a big sentence.

    After trying all these things, I have been able to get through the filter most of the time.

    The spam filter does not take IP information and blacklist you, so there is no need to switch IP or use a proxy.

    I hope this was helpful to at least a few of you.

    Great info thank you! This one has been bothering me quite a bit. What i have noticed the most is specific type of words it does not like. Eg loans, insurance etc.

    By simply removing these words without any other changes, it seems to always then allow the post. What i do in this case is link to a web 2 prop (without any "bad" keywords in url or anchor) which in turn will link to main site.

    Very helpful!

    To get around this, I have always rotated to a different IP which usually tends to allow the comment through once I input a captcha. Your suggestions are a lot easier.

    I've came across a drupal website which has a number of auto approved hige pr 4+ pages. But one day my site's ip get banned since I was too greedy to build many BLs in just one hour :D
    Not matter what I tried, switch to other website I never spammed on that site, change comment text, just put the website into "website" form, I still got banned. Then I found out my site's ip got banned. lol

    One more thing I've been noticing about the Drupal spam filter:

    Sometimes you have to change your url to get your submission accepted. However, if the site you are spamming gives you the option to edit your posts, you can go back and try again. Under the edit function, the spam filter is normally weaker and will allow you post the link you originally wanted to post.

    From my experience keywords like insurance, payday, pills as well as free are forbidden.
