Well the RBLs have trapped a lot of the spammers. Also I’ve put a bit of code in that at the moment is logging the IP of any person accessing the trackback script.
The next step is to take that code and wrap it into the trackback script so that posts containing “banned” words get their IP added to the blocking list.
Well the code is now modified. All trackback posts record the IP of the poster. If the IP of the trackback is in a linked table then the trackback isn’t displayed. This allows me to quickly “block” posts by inserting one IP but leaves the trackback hidden so I can work on it.
Also if I get the same IP posting to the same entry more than once it assumes that it is spam, accepts it (in case it isnt!) and drops the IP address into my spammers table.
