Good luck with that.
The Reg just had an article about how badly AI/DL/ML does at trying to find trolls online because all it takes is for them to change the spelling, make an "accidental" typo, separate the letters with other characters (y*o*u k*n*o*w l*i*k*e t*h*i*s*?) and the AI can't find it.
Now you want to use AI/DL/ML to find $+0ck s(theCentsSymbol)m$? And how do you intend your AI to do any better at that job than the other AI's at finding trolls? You've got the exact same style of hurdles to jump & the same lame runner with one wooden leg on backwards & a swollen ankle on the other. Your AI can barely walk & you want that poor bastard to run a race with ever taller hurdles!
Good luck with that.
