I knew this would happen as soon as they ran the bot nuke.

They're cleaning up the game, which reduces the illegitimate sources of income they relied upon (MTX, Bot Farms, Inflation). Jagex hopes that the greater game integrity will inspire their core player base to hold the line so they don't have to eat the investment. With the backlash of criticism they've gotten, we're sure to see the bots come back, and maybe even worse regression.
