The "Like" and "Follow" buttons on Tumblr require JavaScript, probably to make CSRF harder. A bot that automatically likes posts would need to evaluate JS.
Liking a post on tumblr is just a POST request; it doesn't require Javascript. You can scrape the page (for the content id and authentication key) and submit the POST request to like the content without ever running Javascript.
