I've been trying to solve this for quite a while, it's been about 1 week.

My friend sent this to me to solve it.

• Welcome to Puzzling.SE! Please could you make clearer what the puzzle is here? All we have is the title "rearrange the alphabet" and a string of letters (which isn't 26 letters long and has two Z's, so it can't be the alphabet rearranged). – Rand al'Thor Aug 18 '15 at 8:18

It's actually a very simple shift (caesar) cipher. Just shift all letters by 13 and you get your solution. So when A = 1 and Z = 26 Add 13 to the letter and you get your solution:

Know, your limits, stop bothering me, thank you

Because it is 13 so exactly half of 26 decrypting and encrypting is exactly the same operation

• In other words, ROT-13: the simplest of all Caesar ciphers! – Rand al'Thor Aug 18 '15 at 9:05
• @Ivo It seems that you just became a 2k user. Congrats. – Rohcana Aug 18 '15 at 9:17
• @randal'thor: Except ROT26, of course. – Deusovi Aug 18 '15 at 12:02

It is a substitution cipher which says:
