This is my blog. I own the domain name, I pay for the hosting, and I write the words. As such, I am responsible to any number of authority figures for its content.
With this in mind, I reserve the right to mark up any text I find offensive, off-topic, or just plain stupid as such. In extreme cases, I may delete comments. In cases of recurring abuse, I may blacklist individual IPs or domains.
If you don’t think this is fair, please let me know. On your blog.
