what are you doing to stop boosting?. or it is just part of the game.

I think EA and Respawn do not care must stop boosting with hackers. many players invite their friends with a new account with hack and boost. rank is competitive and we don't want to see fake rank players with newly created accounts with the hack. Ubisoft did great work to stop boosting in rank. if any team member using hacks to win rank will punish their teammate to lost their rank from the season and never get an in the current season and lose elo too.

how hard to stop boosting. in my opinion, you set some rules for new accounts for rank because if any hacker gets ban using a new account hen he brings another fresh account and uses a hack to boost their friends.

add limit. make a mode for level 50 like newcomers. below level 50 can not join rank but after level 50 they can.  it will become time-consuming work for hackers if their new account gets ban and it will add help for the anti-cheat department to investigate because major reports will come from below level 50 and they do not need to investigate much about a profile.

add the same punishment like rainbow six sieges. the player will lose their rank if they are found playing with hacker if they  invited a hacker in their lobby and got ban

I don't think ea and respawn do much care about it because these types of opinions exist in communities from years but dev doesn't apply in-game from the first stage. they know this type of boosting happens in rank. new account with hacks and join with friends and push them to a higher rank. 

too much frustration than fps drop and server lag.
