I dunno, I struggle with the area of what constitutes objectification here. On the one hand, yes they're hired first because they're pretty, but assuming that's the only quality they bring, or that it's somehow baser or less valuable than technical skills seems to me still degrading to an entire group of people who do put a lot of work into both their presentation and ability to navigate socially.
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.
