This ongoing campaign of the hacker community is well-intentioned, but I don't think we'll ever get the term "cracker" to stick. Luckily, the term hacker has gradually come to be an umbrella term for a wide set of skills, capable of both good for evil, describing everything from building web apps to cracking DRM to security auditing, as well as the actually nefarious stuff.

(Of course, this ignores the reality that the majority of ne'er-do-wells have very little technical skill, but plenty of existing terms already fit the bill: fraudsters, vandals, thieves, etc.)
