Comment Form Hacked

Hi. We have a “Contact” link at the top of our home page that leads to a form. I think it’s been hacked or infected because floods of nonsensical comments have been coming into our mailbox, and the “senders’ have ridiculous made-up names like “Tupgoony Tupgoony.” All the comments get sent to our main email box and every day I find it full of this stupid junk. Is there a way I can prevent this without spending any money? (We’re a non-profit organization on a shoestring budget.) Any help is appreciated. Thanks. — Clare Higgins
