Do you think that digital footprints could become a problem?
Yes, I do think that a persons digital footprint can become a problem.
People online can pick up on your routines and habits you do online and start to stalk you and watch what you are doing online. When you were younger you may have done some things online that you shouldn't have done and gone on sites that you shouldn't have gone on. People will always be able to see what you have done online and might use it against you or to your disadvantage later on in life.
You can never take back what you have said or put online as people will always be able to find it somewhere on the internet. Even if you accidentally say something or post something and delete it, somebody somewhere would have seen it.
When you are applying for a job, your employee may look you up online. He/she might find something online that they don't agree with and get a bad impression of you, which may be the reason for them not employing you.
Your digital footprint can cause a lot of problems in many different situations, even if it is by accident. You have to extra careful when you do anything online as it will always be traceable.
