Yet another dot-com has breached the trust of its customers by accidentally releasing the e-mail addresses of those on its subscriber list.

BlackholeTV.com, one of the newest entrants into the world of Webcasting, was made aware of the problem when some of its subscribers complained they had been ‘spammed’ – sent unwanted e-mail – by companies and individuals claiming to be affiliated with the site.

On Sept. 13, BlackholeTV president and CEO Jay Litkey sent the company’s subscriber base a memo apologizing for the ‘entirely accidental mistake on the part of a former employee’ and promising that it had taken steps to prevent such a mishap from occurring again.

The bulletin reiterated the company’s commitment to privacy, but admitted that some e-mail addresses were inadvertently revealed in the header of one of its outgoing newsletters.

Litkey won’t confirm how many e-mail addresses were exposed or even that any were revealed, saying instead, ‘We’re concentrating on the positive stuff.’

The youth culture and nightlife site launched in July, preceded by an aggressive teaser campaign. It offers viewers 19-29 several Internet channels, including Nightlife, Sports, Lifestyles, Street Stories, Music and Big Events.
