Ross, who has over 200,000 followers on Twitter, accidentally included his e-mail address in a Tweet and deleted it immediately, but users were still able to find it through Twitter's search facility.
Twitter users may think they have deleted a posting, but it is never really deleted as all posts are accessible through using the service's advanced search facility, IT security firm Sophos has revealed.
"There is no reason for Twitter to keep those posts and in fact, this is really irresponsible behaviour," said Graham Cluley, senior technology consultant at Sophos.
"In Ross's case, his e-mail could have been scooped by spammers or used by fraudsters," he said.
According to Cluley, this is a gaping security hole in the way Twitter works. Twitter needs to recognise this and allow its members to delete messages from all of Twitter, he said.
Earlier this month, Twitter was forced to backtrack on a change to its settings that caused controversy among users of the social networking site.
The company changed its settings so users could not see the replies of people they follow if they were speaking to people they do not follow.
The move was unpopular, with users saying they used the feature to find new people they are interested in.
