`  ::By making the ``last warnings stick`` I mean't that sometimes these warnings get nowhere.  This individual is an example in which he was warned about vandalizing, blocked for a short period of time, unblocked, vandalized again, warned again...and yes he will be blocked again only to have it removed and the pages vandalized all over again.  I've also seen worse than what he did from other individuals, and on their user-talk pages I've seen enough last warning tags to choke a horse (and yes, that is an administrator problem).  Now, if you truly want these blocks to be preventative, then we do just that.  We work with the administrators to ensure that these preventative blocks stick by ensuring the vandals do not have the access needed to damage the pages.  It's pretty simple.  They damage one day; they get blocked for one day.  They're back doing it the following day, they get blocked for a week, then a month, then 6 months, then a year.  You have to look at it from the writers and editors point of view.  We've invested too much time and effort to make Wikipedia work, and we cannot afford to have some clown come in and damage what we've put here just because he thinks it's funny.  `
