Well said alamb. Many people that were disfellowshipped have gone on with their lives, and many times have desisted from the very thing that caused them to be removed from the congregation.
For example, many begun to have sex relations before getting married but later married. They are no longer practicing fornication. Jesus said, "go and practice sin no more."
If Jesus can forgive us of our sins it is no ones business to hold anything against us.
