Can is it normal accounts ever be compromised?

I do poos in my pants.

Why would anyone want to hack an IIN account in the first place ?

Yes!

A very long time ago, someone must have guessed my (very EASY) password and logged into my account and then changed the password so I wouldn't know what to put in while trying to log in.

I couldn't really get too upset over it because my password was the same as my username, lol.

Only if someone hacked your computer or found out your password.

My password is long and strong, so a hacker would have to attack the site itself if they want to use my account.

That said, I doubt the security is very strong on this site, so someone with enough determination could possibly have their way around here.

It's just that I don't think there is any real benefit to sufficiently motivate a hacker to attempt it in the first place.

If someone has something personal against you, he could easily intercept the connection and use your account as he wishes.

"Nothing is foolproof to a sufficiently talented fool"

I'm morally compromised on a daily basis.

Yes, when I'm stupid enough to leave my account open.

I suppose anything can really. They make special viruses to do this sort of thing. I am sure someone smart enough could hack you if your password is difficult or not. In fact I had viruses on my computer that upon being removed came up as "password stealer".

Leave your account idled and see what happens next.

Compromising positions.

MySQL injection.
I think they use prepared statements though.

It can happen if you have a super-easy password, if you give your password out, or if you are just unlucky.

I think so, I really don't know what happened to mine but I've had suspicions

If you do something stupid like keep logged in to a computer that others have access to or give out your password.

What does that even mean?

Absolutely!
