Hackers topping leaderboards?

On the battlefield V weapon leaderboards there are a couple of dudes called testrandong and LIUAIFENG that are at the top of MANY leaderboards with what I believe to be bogus numbers.

For example: LIUAIFENG is leading the Poignard kills leaderboars with 50,529,028 kills. My god what a talented man…not!

Can this be fixed?

testrandong = 114,514 rocket kills in 31 hours ? Impossible. Thats 61 rockets a minute.
