I don't think you appreciate how low Izo's standards are.
Back in the day when I was on plentyoffish, I found out there was a setting a girl could choose that filtered out any dude who had ever searched for or viewed profiles of girls looking for short term relationships. I thought I was just casting a wide net, turns out I was making myself invisible to the girls I wanted the most. They don't even tell the guys about it. I can't remember how I found out. I think I met a girl IRL who was on PoF and I couldn't find her. Had to delete that profile and make a new one. Anyway, I don't know the answer but I bet that setting would still be effective if it's available.
