I'm not looking for a ELI5 explanation i want to know what goes into circumventing the blocks from the Major ISP. i have a somewhat of a technical background so feel free to use as many jargon terms as possible.
key questions :
What method do the ISP employ
how do they find who to block
once blocked how do the providers override this block
if one provider can do it why don't all of them do the same
how does VPN rectify this
is there something the ISP's can do differently or are they limited to just one method ?
Thanks In advance
