Some general questions from a noob

Hello everyone,

Yesterday I found out about this FiveM project which I never heard before and it looks really interesting. I came up with a couple of questions about this project if I’d ever want to make my own server, hope you guys could help me out with it.

[1] I’ve been playing a few (quite big) servers and noticed they were getting hacked easily. (everyone teleported to jail) Is this a big problem with FiveM and is it easy to patch? What is the cause?

[2] I’m not sure how I need to see FiveM, so like FiveM is the base where everything runs on and you can install plugins and that’s it? The FiveM files don’t need to be changed at all?

[3] Do people ever release pre-made server packages, I tried finding them on the web but couldn’t see anything?

[4] What is the difference between hosting a FiveM server on a VPS/dedi or using a web panel from a host. (the web panel looks really useful for me but I’ve heard some people say they’re not reliable?)
