blocking spiders

[HakkieDEV]

Hi all,

I've been using a small file, robots.txt to prevent spiders from searching my webpage (costs too much bandwith).

Now, it has been working quite well, until recently I saw a spider called "e-collector" was still spidering my webpage.

How do I stop it from doing that?

This is the robots.txt file I used up till now:
===================
User-agent: *
Disallow: /
