I've heard that ad blockers do not work on aosp or stock Roms
.is this true? If not how could one get ad block to work?

Wich adblock solution do you use in KK? topic

So, what adblock solution do you use? Since Google banned adblockers from the play store I have been using AdFree, but after I upgraded to KitKat it's no longer working.

Are there any other apps worth using or a hosts file provider you know of?

Thanks!
