Why are Hackers so eager to harm people

So as you all know I share many screenshots as well as youtube videos where sometimes sensitive information may be missed while trying to show tutorials, so today I get a notification that IP address 199.68.191.106 has gone to my fake server examplewebsite.com and changed the primary email address on the account to oussamahackerr62@gmail.com
Of course I have to suspend the account and block his IP address which seems to come from the US with the service provider Fogo Data Centers.

This is just a warning that this person is out there, and to be very careful what information you share so you don’t land up with the same issue.
