I don't want to point out individual yeshivos but I know at least one (plus one online) that gives smicha to juts about anyone who will pay for it. You spend a couple years for a couple hours at night and the Rabbis there will walk you through yoreh yoreh. Some yeshivos are just so strapped for cash that they will give it to just about anyone who will pay and is not a Reform Jew.
Should 30 year old guys learning in Kollel call 23 year old kids who just got smicha from one of these places Rabbi while they call them by their first name? Where do you draw the line- perhaps we should only call people Rabbi who actually have a career as a Rabbi apposed to someone who just got smicha over the internet or some questionable yeshiva after a year?
