More frustrations in GTA Online

Since I've been grinding my way through research items burning large amounts of money to try and get the unlocks I want I've been playing a lot of GTA online in the week.
It seems like the hacker problem is worse than ever as almost every session I join seems to have someone hacking. Even ones that look normal and seem like they will be a good easy session to just quietly run some cars and the odd supply mission to keep research running ends up with some player bombing me and 10 other players all over the map at the same time then laughing about it in the chat.
