OKC was mainly blocking or declining 99% of people due to drugs, excessive alcohol, wanting sex, existing kids, not being able to read a profile, and/or just being a complete creep. Now granted this could be said for also turning down people in person that throw advances. Though it's a little more daunting when you have 40 new messages a day.
But I met my husband through online so, you know, it's just finding the right person like you would in whatever way you choose to meet people.
