Spam
I don’t know why, but I get lots of spam everyday in the comments section of my blog. The types of spam that I used to get are ones that only have a hyperlink directed to the website, with a few words in the message. But spammers now put crap like this:
Those who assert that the mathematical sciences say nothing of the beautiful or the good are in error. For these sciences say and prove a great deal about them; if they do not expressly mention them, but prove attributes which are their results or definitions, it is not true that they tell us nothing about them. The chief forms of beauty are order and symmetry and definiteness, which the mathematical sciences demonstrate in a special degree.
None of these words are in my block list because these words are used frequently, so its getting really hard to block spam other than preventing people to post comments in the blogs and not get any feedback. The spam comes from a range of IPs and its difficult to block all of them.
Blog spam is much more annoying than email spam.
