Teleportation glitch

I don't know if this is is fixable or if it has already been discussed but today I played a few games of sg as usual, I'm looking at the compass and I see the nearest person to me but he keeps getting further / closer to me pretty quickly (as in moving 50 blocks within a 2 second time period) which I thought was rather peculiar but I passed it off as a simple glitch of my Minecraft as it's been rather laggy recently anyways. I went on playing the game and after looting a few more chests I look at my compass and see the guy from earlier is the closest to me however he was approaching me at extreme speed so I switched to F5. There is just some guy teleporting around to get closer to me so of course I die. I've been told people are able to use this glitch by having their compass in their 9th slot and right-clicking it in 1.8.6/1.8 no optifine. Is this a glitch that can be fixed? It's kind of annoying seeing someone teleporting around during 1v1's as they have an unfair advantage.

 

If there was.. rip SG
