This whole story is interesting. I definitely think that there is more backstory here. Why would someone go out and spend 3-4000 of their own money to do this? If I give him (R'Wolf) the benefit of the doubt that he truly is doing this l'shaim shamayim, why go this route? Did he try to go to Bes Din before making the video?
I hope that the Din Torah, or at least him appearing before bes din will shed some light on the matter
while I appreciate R' Sebags response, and the fact that all of the sofrim in the video have taken him to a din torah, one quote stuck out more than the rest:
We all the sofrim are unified (a miracle) and will do everything to protect ourselves and families.
I hope that this 'everything to protect ourselves' turns out to be that R'Wolf is bending the truth, and not that the sofrim are willing to sell mezuzos that are pasul.
