When entrepreneur Jason Goldberg found out Citibank had deactivated his business account, he did what most people would do: He called, he inquired, he listened. Then he took his fight online.

The tussle resulted in a revised policy at Citi, but also raised a more serious question of free speech – the basis of the First Amendment.

Goldberg’s account was deactivated last week after a review of his gay social networking site – fabulis.com – classified it as “porn.”

The New York-based entrepreneur, who vehemently rejects the “porn” label, said he received no warning prior to his account being blocked and when he first called the bank to inquire, he was told it was due to “objectionable content” on his blog. Goldberg was told the site was reviewed by a Citi administrator who found the “content was not in compliance with Citibank’s standard policies.” Goldberg said he heard the same response from three different Citi representatives.

So what’s a social-media entrepreneur to do? Goldberg began blogging about the issue and including snippets of conversations with Citi officials. The serial entrepreneur, who recently raised $625,000 in seed funding from a round led by The Washington Post Co., said fabulis is a “serious business” and found it hard to believe any content on his blog was so offensive as to merit his bank account being deactivated.
