Shutting down comments

This blog gets one or two spam comments almost every day.

The comments are a joke;

I love your blog.. very nice colors & theme.
Did you design this website yourself or did you hire someone to do it for you?

Plz reply as I'm looking to design my own blog and would like to find out where u got this from. cheers

then a link to promote their own blog, which very likely is just a warehouse for malware.

I tried changing the post, but I don't even think the comments are coming from people. I think they are computer-generated.

So - I'll just shut off comments for a while.
