False logic
"BlackShades was said to be insecure and a tool of inexperienced hackers, leading some users to question whether police resources would be better spent chasing more damaging crime."
OK, by that logic we should't arrest Mafia members until they reach at least Capo status, terrorists until they've graduated to efficient mass killing, etc. It makes a lot more sense to arrest people when they're beginning their career and perhaps (only perhaps) deterring them.
