I don't know, the part about faking interest in order to get their contact info seems kind of like stooping down to their level. I don't think I could bring myself to do that. I might get on their do not call list and tell them straightforward that I am thinking of suing them if they don't stop calling me.
The whole point of faking interest was to figure out who they were, so he could sue them for the first violation and any other violation that occurred after placement on the DNC list.
I did that (faking interest to get their info) once and they harassed me for weeks. If you don't intend to take them to court, I wouldn't recommend it.
