RE: RE: RE: TZeroYou are spot on PTG.
IPs give a location but no more and you can Spoof those in any case
The only thing really would be to require more personal info or an encrypted link ( specific Computer) to maintain or setup accounts- Encrypted Link would cost so not happening and /or
Address Phone plus- SIN#, Passport#or DL# but then most Ppl would not use it and it would destroy SH business model for advertisers so never happening IMO
