They already are... Treyarchs been banning prestige hackers left and right. We just need to report them. ... the problem is that it takes them time to investigate if the person is actually a prestige hacker or not, by looking through their previous games. (Like if they were level 55 prestige 1 for one game and the very next game they are master prestige) Well that scenario usually is a dead give away, but some are not that obvious.
