Yes, it is possible. Eg, if you have a script earning 200k p/h, you would only need to bot for about 4 hours to pay off the bond. You just need to be careful.
Is RID bots low ban rate? they claim to be "Undetectable"
As far as I know, every bot out there claims to be less detectable then all the others. No bot is " undetectable " though, if you bot, there is always a chance of getting banned, no matter what precautions you take to avoid it.
Any bots you suggest?
Not really, OSbot and Tribot are the most common and there is also lots of smaller ones: http://www.sythe.org/runescape-2007-cheating/1555983-past-present-future-bots-old-school-rs.html
Is RID bots low ban rate? they claim to be "Undetectable"
I know this used to be the case (not sure if it still is), but RiD's bots take control of your mouse and work within a web browser, not a client like most other generic bots. It most definitely makes the bots less detectable, but only allows you to run one account at a time, which cannot be ran in the background even.
