You guys understand that they won't ban your main if you're on a flagged ip because you could be in a house with a bunch of runescape players. Some who bot and some who play legit. That's why they won't wave ban.
If you play legit on your main and have never botted on it, ye. It's safe. There is no ip bans, only wave bans where you'll lose all bots on the ip; not legit accounts.
You're completely fine if you dont bot on your main
Protip: if you wanna get good you can't just ask questions.
The good farmers don't leak what they do, what makes them successful. You need to find that out for yourself. Gotta work for it
