I would say curiosity got better of the OP. "Looking" at those websites they spam is how you got hacked most likely. When you go to them it installs a "cookie"....It isn't possible to just randomly type in someones password AND username. To the OP, mate SE will not ban you for looking at those sites, but the stupidity factor might get you laughed at. I would suggest you run scanners, delete ALL cookies from your history. Everything, saved passwords the lot. Then change email And password again
