Guido Fawkes on moderating his blog comments

Guido Fawkes on his blog today says why he has introduced software moderation to vet comments.
He writes: "Temperamentally Guido would prefer it to be totally free without any limits. In practice the place would be over-run by 9-11 troofers, Jew-haters, Jihadis, muslim-haters, old fashioned racists and loonie lefties, who unable to get an audience of their own, try to parasite off Guido’s readership.
"The limited software moderation we have was introduced to stop them and to prevent the likes of Derek Draper accusing Guido of deliberately promoting whatever was written in the comments.
"In truth Guido is sceptical that it really matters what some window-licker writes in the blog’s comments and the majority of the blog’s readers don’t read the comments. People who complain to Guido that they are offended really have (a) no right to not be offended (b) no obligation to read the blog."
