Sure they will. Using the automated programs like XRumer and literally thousands of botnet zombie computers, programming a 60 second stall between filling out the form and clicking "submit" won't be all that difficult and really, won't hurt spamming efficiency. It hasn't happened yet because time checks such as this - which have been around in one form or another for years - just haven't been in widespread use.

If vBulletin or any major message board software has this time check in its native code, it won't be long at all before the botnet administrators start programming a delay into their systems.
