Loveint is when a person who works for the government sneakily looks at someone's private information like what they're saying online, how much they get paid or what they look like.
It's not allowed and is very bad because people's private information is supposed to be kept safe and secret. It's like if you had a toy that you really liked and someone came and took it without asking you. It's not fair or right.
People who work for the government are supposed to be responsible and keep all information private, just like how your favorite toy is for you to play with, not for someone else to take away without your permission. Loveint is when they fail to do that and do something really bad instead.
