custom form with text field named 'name'

So I have a form on a clients site with a text field input with a name of name e.g:

<form action="" method="post">
  <input type="text" name="name" />
  <input type="submit" value="Send" />
</form>

For some reason wordpress decides to do something with the “name” field and destroy the posted data. If I change the name of the field to “name2” everything works fine. Having looked at a load of documentation I can’t find anything that suggests wordpress uses POST data with a name of “name” for every page. Anybody have any ideas?
