Back in 2013 on GTA V, I used to get booted very often by this one player named "WaterBoy", he'd sit in public lobbies waiting for me. This guy was after me!
Until one day, I discovered that VPN's stopped this asshole from grabbing my IP, so I went on to purchase 'PureVPN'. (This VPN has been good to me), I configured it to my PC and linked it to my PS3, I went back online...
I'd go into a lobby to find that asshole WaterBoy again but this time, he couldn't intimidate me. He proceeded to try and hit my VPN IP instead of my REAL IP, who's laughing now script kiddie! He eventually proved he wasn't as advanced as he thought and quit the lobby, I never seen him again.
I recommend PureVPN to all players having this issue with these 'Booters' or any trusted VPNs. I've never been booted since the day I bought it.
