How does a website hack your account in the first place?

[Da Trollerâ„¢]

I got a spam message on twitter saying stuff about my account I clicked it i was signed out of twitter and could not sign back in same went for this account i finally got it back but cant website owners get in trouble for that or something?

[thankfulplayground830]

some people thats all they do is sit and make web sites that look real.. and once you click on them they have your IP address ...then with that they can hack into your stuff

i always get emails from Wells Fargo saying someone is trying to get may acct info .. i dont even have an acct with them
with my regular bak i get them saying someone tried but got the questions wrong and other stuff ..

i asked and they never ask or even call and ask for that info

never give out anything to something like thta because it may look real but most of the time its not
