The other part is that I don't think it's wrong to allow the GUI of a person to be the initial draw towards someone else. If that's all someone wants, then they're shallow and objectifying someone.
But for as many guys in SV who are pervs only out for one thing, I'm willing to wager that there are just as many, if not more, introverted SE's who actually don't mind a more personal connection, however momentary, than to just get their rocks off. Sometimes it's nice to have a short, if meaningful, or at least interesting conversation with someone so far out of your league in traditional social contexts.
I'm not trying to be an apologist for this practice, I just feel that while it has its own innocent value, it could be implemented in a way that is a bit more transparent and helpful long-term to what is behind some of the motivations for this.
The issue is the gender disparity in _software_engineering_, which is actually made worse by this, because hiring someone because they look pretty (they're not asking agencies for, like, conversationalists with master's degree, and if they were, they'd still have to be attractive) is straight-up objectification, which is bad for women everywhere - and men.
