When high level kills low levels

Hi, I used to play before on Molten, on Lordaeron and even then i had come across many, many players that seems to be max level, who didn't even hesitate to kill me if i was lower level. Today, that topic seems to be still around on Lordaeron. I play strictly horde and even in my 80s, I never liked, not even been tempted to kill a low level. Whenever i come across one, I would avoid them cuz they're leveling, doing quests and things. Once they are 80, we can do bgs, arenas etc. So, today i come across this guy, Alliance Hunter, and he camps me. he is obviously max level and I'am 68, just a dk leveling the mining skill. So, how can we find a solution about these, as it seems to me, people who enjoy showing their strength and killing lowbies?

Can i post link with some screenshots?
Should i report them or smth?

There isn't, it's considered part of the game. Call people to help, ask for help in your Guild, etc.
No.
No.

Thank you for the information! Best of luck!
