We are all familiar with the phrase "The internet never forgets"

I try as much as possible not to judge people especially their past because I also am not perfect myself.
But lets be realistic, there would always be trolls, bully's and people with different opinion on the internet so as much as possible, it is advised to leave a good digital footprint. It is hard and even impossible to wipe them off.

I don't judge people because I understand people change paradigm but I can't speak for other audience in the internet. So as much as possible, every tweet, every image or video should be thought through well before being posted on the internet.
