They changed their name to catch the 'green dollars'. I used to work for them and I know that they are a fake company. They use the same high, energy-hungry servers like anyone else, even a little older and less-efficient than many others.
GreenGeeks should be - DirtyBrownGeeks. Don't trust this company or any other reviews that it pays people to do online. They are borderline scam. Go for a more reputable company and get some work done for you cash.
