My pet peeves is sunglasses on every pic & I'm totally with you on the dead animals. I was on Plenty of Fish for awhile & Oregon men really take that fishing metaphor seriously with their photos!
I tend to look for people that I can imagine kissing without recoiling to save my time & that's tough to do with sunglasses hiding who they are & thoughts of fish smell, lol.
Now that is a great strategy! I think i do something similar, because sometimes the instant response is "eww, no!"
