Suggestion : Don't message the people whom you've already messaged if you run the same CSV file for a second time.

Do not message people whom you have already messaged if you run the same CSV file for a second time. This is because you will have to run the file again anyway, due to a flood error. If you restart the code in VS, the people who you have already messaged will be messaged again. This is because the code will start from the beginning of the CSV file.
