Anyhow, Google does offer tools to remove such.
As to the "none of my usernames or emails are being recognised." that's for you to work out with your web host support folk.
I have a bit of a conundrum for you. This one sounds pretty straight forward but I think it's a little complicated. Please stay tuned!
A while ago I created a website (squareeyedpictures.com) but decided the name was too long so bought a new domain (www.sqep.co) and put a redirect on the old name so that if you type it in, you will automatically be taken to sqep.co
Anyway, now when I search "Square Eyed Pictures" on google I can see both sites come up, but I only want sqep.co to appear.
I have done some research about meta tags etc, I believe this is how I would change it so that Google won't list the old version of the site. But I can't for the life of me work out where to even change these meta tags.
The old version of the site was hosted on hostgator and I used wordpress to make the site. The redirect is through godaddy. I figured that I should try and get into the old site's wordpress panel and from there I could change the meta tags. But the problem is that I can't seem to get into the old wordpress site. Because squareeyedpictures.com is being redirected to sqep.co, when I type in squareeyedpictures.com/wp-admin it just takes me to sqep.co/wp-admin. I seem to have managed to get into a log in page for squareeyedpictures.com/wp-admin but none of my usernames or emails are being recognised.
I am so stuck here, I don't know what to do to get that site of google. Please help!
