When running a website as this with the capability of audience participation, you pretend that you give people the chance to voice their opinions. And unless you have problems of some sort, you'll be fairly tolerant towards what you let people say. They'll be able to point out errors, mock you, prove you wrong &c. They may even start presenting their own theories as a followup to a post of yours. You may not agree but that's part of the fun.
And then there are the spammers. They somehow ruin the illusion that we are completely open to what people can discuss on our sites. I try to simply delete everything that looks like comment spam. Not very tolerant, but I like it. In fact, I even did the upgrade to Movable Type 3 just because of the comment moderation. It's not very convenient but – unfortunately – necessary these days.
The bad thing about comment moderation is that it reverses the burden of proof in a way. Before comment moderation I could skim through comments and then had to act on those I considered inappropriate. With comment moderation, everything is 'awaiting approval' to begin with. I'll have to decide in favour of a post before it can appear on my site. Of course I try to be open minded about this, but recently I've seen quite few apparently non-commercial, non-insulting but plainly absurd comments. I don't see their point and they seem to be a waste of time. Somehow it itches me to not have them on my site. But then that'd be wrong as well...
About once per week I get comment-spam bombed, but it’s usually only a few minutes work to clean it up. You seem to have attracted a second form of online moron, what’s referred to (I first heard this term on Slashdot) as a “crapflooder” — people who post (sometimes with automated tools) complete and utter gibberish.
I know you hate to be a content cop, but I’d delete the stuff from your comment queue if I were you — it serves no purpose, gums up search engines, and occasionally you’ll find people hiding spam links inside the nonsense.
That ‘crapflooder’ thing sounds funny. Although I don’t quite get why people would do this.
Probably you’re right about deleting the comments.
Especially the latest nonsensical one is just dumb. Some of those posted before (FBI…) were quite funny, I thought.
