If you see a person that is only around lvl 200-300 with high stats (5k-10k of any stat), let me remind you that there are in app purchases in this game. You can get 90m ( which is 450 tix Which is like 20 bucks or so) and it's already worth around 1650 books, and if you are an adult with a full time job, or a kid with an american mommy who is willing to pay for your minecraft server's vip privillege then 1650 books is easily obtainable for you. Just pointing that out, think twice before reporting.
Now real quick a disclaimer, i'm (god forbid) not saying that book duping isn't a real thing and a problem. Just letting you know that by being uncareful you may get innocent people who spend a lot of money to support this game get banned, or you just might take up administrators' time and delay a ban for somebody who deserves it.
