I just had a look at my statistics. I use Askimet to detect spam on my blog and to hold it in waiting until I evaluate it. Every once in a while a message is misclassified. That is, a real comment is categorized as spam or spam is classed as a real comment. In any case they are not deleted or published until I have looked and decided. I would say Askimet is correct well over 99% of the time.
But in looking at the stats over the past year, I noticed that the volume of spam has gone way up. A year ago, it was hundreds of spam comments per month and the past few months have been several thousand and the number seems to be increasing.
I’m not sure if this is a general trend or just happening here. Have other bloggers noticed some similar?
