Okay, I know the creators are trying to sing a different tune now about its intended purpose and the whole thing may very well be an elaborate hoax to garner attention for their vlog anyway, but going back to the original concept and considering the possibility that it might just be real:
Let me get this straight. The way it was initially conceived, basically anyone who has a cell phone number that they can presumably claim is mine can create a page in my name and rate me?
Is there supposed to be a way to verify that the number truly belongs to the person in question? If not, and there's a 48 hour window to defend one's self in the event of a negative claim before it's permanently posted, is the person notified via their supposed phone number or what? You're SOL if you have no idea? If this hypothetical alert is disregarded, is that considered consent then?
Let's be real, if that's the case, all it takes is one vindictive ex/former friend/angry customer/whoever with their technologically inept grandparent's cell phone number, and bam, Granny's number is now connected to someone who's unaware there's a smear campaign on them via this app. Hell, someone with enough money to throw around and a big enough ax to grind could do this with a cheap pay-as-you-go Tracfone or the like, maintain control of the whole operation, and keep the concerned party out of the loop totally. Scary!
Furthermore, if someone is made aware of a page created in their name, the only way to gain (limited) control of it is by forcing them into joining a site they probably wanted no part of anyway? And STILL no way to opt out even then? That's such utter bullshit.
Stuff like this makes me so glad I got out of high school before social media sites and apps became so prevalent. I'm mostly a non-entity these days, leading a quiet, mostly solitary life who probably doesn't have to worry about someone doing this to me now, for good or ill, because even most of my family tends to think of me last and my love life is nonexistent, but god, during my teenage years when e v e r y t h i n g was a major drama? I can only imagine. Between the sadistic rich snobs in my class who would've delighted in this sort of thing just for the fun of it, and people like my very charismatic ex who decided he didn't want me but no else should want me either and quietly persuaded almost every interested guy in three graduating classes that I was to be avoided? I shudder to think how much worse such situations would've been if any of them had anything like this as a tool at their disposal. This is ripe for bullying and abuse.
