How to prevent accidental clicks in the Save button when saving a node? I need to prevent accidental clicks in the Save button when a node is being saved.

I found this module  which does exactly this. But the problem is that it uses javascript (jquery). Then if the user disable javascript this module is useless.

My problem is that in my website the user get points when creating nodes, so I have to prevent this in a more secure way.

How can I do this? 

What do you think of these ideas?:

1) Maybe I would forbid the node being saved more than one time    programmatically instead of disabling the Save button. 

2) Or better: I would allow the user to just save a new node every 5 minutes.
Finaly I got this  using these 2 modules:

http://drupal.org/project/hide_submit (to prevent clicking the bottom using jquery)

and

http://drupal.org/project/node_limit (just for browsers with javascript disabled) This allowed me to set a time interval limit to post new nodes.
