Ok, I surrender
I decided to disable comments alltogether on this blog. The amount of time required to manage the ip banning and deleting the spam comments is getting too much in comparison with the small scale blogging i do over here.
I just dont have the time to go to war on this and keep securing the blog, while giving others the opportunity to comment on the postings. My apologies to the serious commenters. Please use the trackback facility to be able to refer to the postings which you want to comment on.
