The first alpha versions of my new WordPress comment plugins are now available for download.

Comment Timeout 2.0 closes comments on posts on your blog a certain time after they are posted. It has been rebuilt from the ground up to incorporate some new features:

• You can now override the default settings to allow certain posts to have the discussion kept open for a shorter or longer time, or even indefinitely.
• You can define a “popularity level” above which the discussion can be kept open for an even longer period of time if you so desire.
• You can have comments on older posts sent to the moderation queue instead of closing the discussion altogether.
• The comment form now indicates when the discussion for a particular post will close.

Some features were added to version 1.3 but have now been spun off into two separate plugins:

Three Strikes and You’re Out examines your Bad Behavior logs and your spam queue and closes comments across the board on your blog when you are visited from any IP addresses that have been repeatedly misbehaving (the default settings are three times in a week). It also defines a couple of hooks and adds a new logging table to the database, so other plugins can register naughty events (e.g. failed captcha tests) or override the counting mechanism (e.g. to implement whitelists or blacklists).

Link Limits rejects comments which contain BBCode or more than two normal hyperlinks. I’ve found that this blocks approximately 80% of spam, yet genuine comments exceeding these limits are almost non-existent. It informs your commenters that this restriction is in place. It also logs any violations to Three Strikes And You’re Out, but it works perfectly well if you do not have Three Strikes And You’re Out installed.

I’ve marked them all as “alpha 1″ status, which means use at your own risk, though I am dogfooding them on my own blog. If you have any problems with them, I’ve written a post on how to report problems with WordPress plugins — please read it before giving me a shout, though I do welcome feedback and suggestions of course.

Starting with these plugins, I have changed the licensing terms. Whereas the old versions were GPL, these ones are available under the MIT X11 licence. It is GPL compatible but doesn’t have the “copyleft” element. This means that if you wanted to, you could adapt it for use with another, non-GPL, CMS or blog program.

A colleague of mine mentioned to me the other day that I ought to read The Mythical Man-Month by Fred Brooks. I haven’t done so yet, but I was interested to see from the various reviews that it talks about the “second-system effect” — that the second version of a system that you design will tend to be over-engineered, since it has all the features that you thought about for the first version but didn’t implement due to time constraints. It means going from a small, elegant, successful system to something large, feature-laden and bloated. Scope creep, in other words.

I’ve been thinking about this as far as the next version of my Comment Timeout plugin is concerned. The original idea was quite simple: to close comments on your blog entries after a certain length of time. The current version has extended well beyond that remit, with a whole bunch of other features that, while useful and maybe related from a technical perspective, aren’t really related from the end user’s point of view to what the plugin is ostensibly trying to do. I wonder if this is probably a bit confusing for users and making it a bit difficult to determine whether issues are due to bugs in the code itself or people misunderstanding what it’s supposed to be doing.

I think the answer is probably to separate it out into different plugins, each of which concentrates on doing a single thing and doing it well. At the moment, I’m thinking of separating it into three different plugins, perhaps something along these lines:

• Comment Timeout 2.0: a trimmed-down version, which concentrates solely on the job of closing comments on old posts after a certain length of time.
• The Black Hole: the functionality to nuke comments altogether if they contain BBCode, too many hyperlinks, or certain keywords, so they don’t even make it as far as your spam queue.
• Three Strikes and You’re Out: the bit that examines your Bad Behavior logs and spam queue and closes comments to IP addresses that are persistently causing trouble.

I’d be interested to know what people think of this idea. Would it make it easier to understand, or would it just make things a bit more confusing? Leave me a comment and let me know what you think.
