[Savannah-cvs] [SavaneTasks] (edit) randomized text fields: limits

[Beuc]

??changed:
- * randomized text fields:
   * cons: our site configuration is public - make answer as regexp instead of 
strings, so they can't be copy/pasted

 * reduce number of links per posts + surge protection (limit msgs/min)

 * URL block-lists?

 * randomized text fields, this prevents reusing the form

++added:
  * limit: can't spammers just grab the form and fill-in the fields in order, 
like humans do, only with garbage? Does this really help? We already have form 
ids to prevent double-posting forms.


--removed:
- * reduce number of links per posts + surge protection (limit msgs/min)
-
- * URL block-lists?
