There'll almost certainly be a temporary lull.
How many bots get disabled and for how long is a different question.
Jagex probably know about the big bots like rsbuddy, so I'd expect it to get hit. However, if there are private bots that aren't common knowledge - they'll probably survive...
I think bots help the economy in some ways. For instance, if you need ashes or vials of water for herblore, you can be certain a bot did them.
However, when it comes to resources that people really compete for I dislike bots. Makes it harder for legit players to get stuff like coal or other...
Could suggest hill giants for higher level range and magic. Just safe spot them and you get big bones and limpwurt roots which makes good gold whilst you do it!
I don't get why anyone would continue botting after the announcement on a proper account - you'd just wait until a week or 2 after when the bots are probably fine again without risking anything. Botting up until the last minute is just asking to be banned.
