where/how do people get their blur bidding bot?

that's understandable for the reason that we all might know - who wants more competitors..

but at least may i ask that how did you acquire your bot? is your friend a dev?/you're a dev and scripted it yourself?/you bought it from somewhere? (if this one, could you tell me sir?)/you found it on the internet or so? ty agn

people seem secretive about it
