I’d rather be blogging about something else, but after a raft of stupid “Neat Blog”, “I agree”, “Cool Blog I’ll be back” comments, often from the same IP with faked emails, appearing on very old posts (ones that pop up on Google), I have taken another level of blog protection.
Taking a cue from Greg’s effort, I have set up a close comments script that de-activates the comment forms on entries older than 30 days (using a PHP script described at geeksblog but the link has actually moved elsewhere). It is pretty easy to set up for MT blogs using mySQL. (Note to Greg- you need to run this as a cron job to keep closing comments off).
This is not too horrible as there are hardly any relevant comments that come more than 30 days later. It does not quite close the comments door as far as Stephan warns but is a step I can live with for now.
