yes, they do, I am also fed up with this, but if I am not wrong, it is required cert giving organisations, they sometimes even do video kyc.

you can try to find a good free subdomain, theey would just ask for a email, but that would be a subdomain, and nothing more

would love to see some pictures

these are people you should be scared off

epubs are effectively self contained html files, but the scripting is not there (afaik)

to add to it, you “can” add anything arbitrary, but it is not same as downloading a executable. Due to some really weird reasons, many parties were interested in using pdfs like interactive forms, for example some government forms, where you can fill a field, and you can add scripting to execute upon input and convey back. It is somewhat like javascript for pdfs, and then the onus is on the pdf readers to be compliant enough to execute such scripts, and provide enough access to your system. Many minimal pdf viewers do not implement these features, or for example pdf viewer in firefox has the option to execute, but disabled by default.

well that gives me some soothe

my family is dying and i dont like it, atleast get me on the tracks with them, would not be able to live with the guilt anyway
