Social media users posted many more negative opinions than positive about Bank of America and other large banks in the US and Europe over the last 12 months, according to a new report from social media analytics company Amplicate.

The report found that 87 percent of all opinions on social media about Bank of America were negative over the last 12 months. Other banks did not perform much better: 83 percent of opinions about major banks in the US and Europe were negative over the 12 months, with only Citigroup avoiding complete loathing.

Citigroup was the most loved major bank on social media over the last 12 months, with 39 percent of opinions expressing something approaching love for the US banking giant.

ING, on the other hand, was the most hated bank on social media; 97 percent of opinions on the Dutch bank were negative over the 12 months, with Dutch social media users accounting for nearly all the hatred. Although ING was the most hated in percentage terms, many more negative opinions were posted about Bank of America, which was by far the most talked about bank on social media over the 12 months.

About 40 percent of all opinions about major banks in the US and Europe in the last 12 months were comments on the American bank.

Hatred for Bank of America reached its height in December 2010, when social media users objected strongly to the bank's decision to force the closure of numerous websites expressing loathing for the bank. Only 8 percent of comments on Bank of America were positive in the month.
