Do You check Profiles Before selecting Best Answer?

I was Just curious..I have asked this before and mentioned That alot of the people here will answer a question and state..I have painted 20 years.Or I am a electrical contractor..on and on...But in the same event I am a avid profile searcher before I select a best answer..and often find when I come across a question asked That someone answers that I know is 'bunk" I look at thier profile ..I find that that same person just answered a painting question saying they are a paint contractor for 20 or 30 years..then by searching the profile I also see other questions they have answered..and they were an electrician for 30 years the day before,or a concrete finisher etc...whatever pertains to the question asked..it seems they are that particular type of contractor..When I posted this before, I found some of the people in mind..I will mention no names....have then gone in and made thier profile,questions answered and asked private to where you couldn't then view them..for they have been exposed..And may a say..a couple "top contributors" at thatOne of thems favorite phrase was " I ahve done carpenter work every day of my life..and the next question they answered ..they have done electrical work every day of thier life...I suggest if the answer is questionable ..search thier profile and look at thier other answers..or see if they chose to make them "private"..this is the first clue..Anyone else do this?
