I normally won't reply to an ad if it is more than three days old.  On occasion, the girl has already been arrested or is off that day.  But I will take note of girls and their phone numbers and wait until they repost in the future. If I see they were arrested, I avoid them because they may be working to set me up.  Of course, that requires a lot of homework to find their name or search through mugshots in all three counties by me.  The oldest?  I found a girl two years old ad, and when I got her new number and ad I got her that day.  She is currently incarcerated again, but I got mine in beforehand.  Look up my posts...Her name is Hannah.
