I wouldn't block the website, partly because any kind of reaction from you might stimulate her interest.

I did a quick search for your name, but didn't get very far - possibly someone knowing you better would know what to search for. It's worth checking your online presence yourself. I had worried that your old contact details would still be in google's cache, but your website isn't very google-friendly. She may have kept copies herself from before you removed them, but then again she may not.

The only other practical advice is to keep records. Note down events and times so that if ever you do need to take formal action, you can show a history of the stalking (if that's what it is/becomes).
