My old username has been blocked
To many login go through system again.
Then u cant get through.

There should be a captcha or something you need to click on to verify yourself, I don't know. Sorry, I really don't have time today to look into it too deeply but I can't do much about it anyway. Maybe give it a day, try again. Perhaps check the box to remember your password so you don't need to type it in every time.

I know it's a pain in the ass (security is always a tradeoff with convenience) but there is just no alternative. Without captchas and long password requirements, accounts inevitably get hijacked. :(
