Help about automatizing process of account creation/posts on article/web 2.0 sites

I need ideas how automatic account creation can be done on article and web 2.0 sites. It can not be done with PHP/Curl, because many of those sites use ajax/javascript, and this is not possible to be done via curl. So, if anybody have idea how this could be done and with which tools(in linux enviroment), please suggest. I am thinking if than can be done with some HTML Layout engines(like Webkit or Gecko, or maybe some simpler one). It must be possible to access en开发者_Python百科gine API, so we can simulate clicks, enter url and so on.

So, is this possible(it should as senuke did something similar but based on simple version of IE).

Thanks in advance.

Have you looked at Selenium?

It starts as a simple plugin for firefox where you can record and replay scenario's, but you can use the script in lots of programming languages so you don't even need firefox anymore.
