Thought members might be interested in part of the technology behind the site and how we stop as many spammers as possible. Forums are often targeted by spammers as they allow a good way to get the spammers products noticed by a target audience who might be interested in what they are selling/offering (or pretending to).
On Ausphotography we have several levels of anti-spamming technology. One of which is that AP checks all new registration attempts against a global database of known usernames, IP addresses and email addresses. When this software detects a match, it returns a response to the person/bot trying to register on the site, advising them that we actively block spammer registrations and that they cannot register on AP.
If a spammer does get through and posts to the site, we remove their post, ban them, and report their details to the global database, making their IP address, username and email address combination, effectively blocked from every other site that uses the database.
Here is a screen grab from this evening of a section of the new registration spammer detection at work. Note the times of registrations. We block a spammer every few minutes. This continues like this 24/7.
