A few weeks ago my blog was getting inundated with spam. Until then it had been at a manageable level with only two or so comments every couple of days. However when I was on holidays I actually had a backlog of several hundred comments and it took me a good hour and half to work through cleaning them up.
The problem you see is that I didn’t have a good way of deleting them, the .Text interface is pretty slow and the posts were all over the place. After cleaning them up I downloaded and installed RDOS into the site. Since then I have only had two spam messages – both of them using alternate spellings specifically to fool the filter.
Overall I am pretty happy with the results.
