Another thing I found useful during my online dating adventure: have something in your profile that gets them to qualify themselves right of the bat.
I had this in my profile...you should message me if you can run in 6 inch heels,have a sexy smile and a sense of fashion.
So youre asking yourself wtf BL what's the point? Well it shows that you have standards but in a funny way.
I was messaging girls and at one point during the convo this would happen most of the time:
Girl: blah blah you seem fun but I can't run in 6 inch heels
Me: its cool beb. This way if you turn out to be crazy in real life I can outrun you
They ****ing melt after that.
EDIT: replace crazy with serial killer/ax murderer/craiglist killer etc
