Depends on word usage. 40 years ago, using a kitchen gadget in an unintended way was called a “trick”, and now it’s called a “like hack”. This was a “tech hack” — in other words, gathering and using data in a way that was unintended. And it uses a “contact hack” because reading the screen shot you’ve included purposely lacks context that would cause someone to question their choice. So technically no, not a security breach type of hack, but definitely a social engineering hack. And I think therein lies the problem. There is a lot of effort that goes into building social trust (this app is OK because it passed the test to be included on the platform; this platform is OK because they keep reassuring us that x,y,z), and then when that trust is broken, there is a lot of throwing up of hands and disingenuous backpedalling.
