it's riddled with scams, and thinking any of this will detect any of the things you mention is very foolish, native and show a total lack of understanding of the scams. of you think using a proxy is essential for visa scam, i would even know where to begin to correct you.

it's one hundred per cent clueless privacy invasion. they are probably also opening ports via other means and using that for side channel ID like Facebook does.

just like any other documentation scam, the only weak point is on the "last mile" that's why you will always have a human interviewer.

the visa process is abusive and unpractical because people will work around any hurdle and their kpi will never be affected no matter how crappy they manage to make to whole process. or how many doge kids implement useless privacy invasion tech just because.
