Also note that all the quotations were from public shiurim that many people attended and were free to take their own notes quoting anything the Rov said. The only service from this place (and it is a very praiseworthy service) is to transcribe what the Rov said in those public shiurim that anyone was free to attend and write down (and later share with others, if so desired.)
Btw, the TorasAvigdor website is not affiliated with Rav Miller’s Yeshiva, family or with Simchas Hachaim. It is a private effort by regular talmidim of the Rov who want to disseminate his Torah on their own.
