Y'all are assuming I'm implying things that I'm not implying. Allow me to clarify:
1. Just because your account is flagged does not mean you will be banned.
2. The more time that passes between bans means the chances of being flagged is less.
3. Story Time
Over my 6 years of botting, I've botted over 10,000 hours and received bans on over 40 accounts. I also use to operate a gold farm of about 20 accounts. I monitored my farm very closely, and one day I witnessed my accounts being picked off, one by one, across different worlds. After about 14 accounts were banned, in front of my eyes, I force killed the remaining 6. All 14 accounts were perm banned. The 6 that I forced killed were not banned, and are still unbanned to this day. All the accounts were operated on the same IP. I also continued to bot on other accounts I had, none of which received any blackmarks.
Ultimately, being flagged doesn't necessarily mean you will be banned, even if you're continuing to bot. It simply means the risk increases. Also, unless you have someone inside Jagex, there's no way to know for sure or prove that your IP or accounts are flagged.
