I had to take the contact form down. Okay, I didn't have to take it down, but spammers either found a new way to abuse these things or they've just now discovered my page. For quite a while, it served its intended purpose with no trouble, but lately the spam has been increasing steadily and I'm tired of deleting their broken-English attempts to sell me herbal remedies and weird random things I don't even understand.
Now there's just an email address in the sidebar. Hopefully the parasites haven't already evolved a resistance to this format. I'm sure they will eventually.
