i"m getting paranoid i think. i'm getting constant mails of people trying to access my gmail accounts, game accounts etc. so that must mean i have leaked my username/password somewhere in the past and i'm affraid i might have used the same combinations for my btcjam/gox/blockchain accounts etc.. even if i change my passwords the log in attempts keep coming ...i don't think anyone has had access to any accounts of mine besides an old wow account were i fel into an e-mail scam like 6 years ago.. should i be worried?
Keep in mind that these emails about people attempting to gain access to your accounts are phishing emails. In other words, the only people trying to get your accounts are the people that sent you the emails. I hope you didn't click on any links in those emails.
