The Wayback Machine isn't searchable, or at least not nearly as searchable as Twitter itself. If I have a fight with you now, I can just go to search.twitter.com and put in "bad word from:AzzieElbab" and find any of your bad tweets. To use the Wayback Machine to get you in trouble, I have to know ahead of time what you said and at what URL to use it against you later.
