Akismet is the spam filter that I and most other people use for WordPress. It’s working wonderfully – for me, I’ve had no false positives, and it seems to catch everything. Spam sucks, but Akismet gets rid of any annoyance.
I'm a mathematician, but apart from that, I'm a fairly normal guy. I used to write a blog - this blog. I write (wrote) about whatever is on my mind. It can get quite personal sometimes.
