Indeed. This would become the first question I asked a woman when trying to date. If she's childish enough to use something like this, I'd have no problem saying sayonara. There should be some expectation of maturity and general couth in any relationship.
Yes, it does. I have standards for the people I choose to involve myself with. In a similar vein, I would likely not even befriend anyone that uses it, or anyone that supports this type of application (either directed towards men or women). A big part of maturity is having personal integrity in all dealings. This means, for me, an automatic rejection of anyone who would use something like this. Similarly, I do not befriend constant gossips or complainers, and call my friends out when they do it. Certain people are a waste of relationship effort.
