i'm guessing you skimmed through my message.
i didn't say not to get a residential ip (proxy), but just one that is different from his own. that way when the account gets banned jagex see that it was "clearly" not the original owner playing. and i have gotten each and every one of my accounts quashed at least once (some even twice), except for one, thanks to the fact that i'm using a foreign ip.
i agreed that a private script would be better, and gave an example, but also the reason that it's not something that everyone does.
the long term botting of 80-85 to 99 magic was an example of someone using a PRIVATE script. it is not something that you'd realistically achieve using the public ones for zulrah. my best results with zulrah botting have been with longer sessions so i am speaking from my own experience, also basing it on what i'd commonly see in fruity's discord server.
