Hey there!
Hackers are a definite problem- no doubt, but when it comes down to it, they're extremely hard to keep under control.
Moderators file hundreds of bans every day, and it seems like for every banned hacker, two more join. It's nearly impossible to completely eradicate hackers.
The staff is doing their absolute best, and so is the community. You can help the staff in the effort to remove hackers from the server by recording, uploading (as an 'Unlisted' YouTube video) and posting a
'Report Abuse'(
http://www.minecraftsurvivalgames.com/forums/Report/) on the forums
Past that, there really isn't too much that can be done. Everyone is doing their best, and what we ask is that you stick around. Someday, it will get better, and we hope you'll soon be able to play hacker-free games
Feel free to poke a moderator on team speak with the name of the hacker, and the server, and they will come take care of it

That's my standard 'hacker complaint' response

To talk more about your other points in the thread, simply put, if you aren't enjoying yourself, take a break. Try some other MCSG game modes, or just take a break altogether.
Whether it's worth it or not is entirely up to you, but if you are not enjoying yourself, I wouldn't say it's worth it.
There is no way that every game you play, there will be a hacker, and just because you don't win every game doesn't mean it's any less worth it, or fun, but that comes down to personal opinion.
Do whatever makes you happy
