This is exactly it.Ehhhhh this is pedantic enough to not really warrant all the energy you're dumping into it, you're kinda dying on this hill over a technicality in phrasing. My claims are quite generalized, but they are based in evidence and anecdotal experiences from many people. It is Extremely rare to the point of insignificance that a cam model would genuinely want to meet, fall in love with, and marry a viewer with no ulterior motives, or outside of a sugaring/escort situation.
There's also the larger ethical issue of trying to dissuade poor thirsty saps from thinking there's a chance so they don't try to initiate unwanted romantic relationships with models or fall for scams.
