Bercow's husband, the Commons Speaker John Bercow, and others warned her to stop using Twitter after she was embroiled in a series of controversies over messages posted on the microblogging site.
Last night, she tweeted: "Looking at tweets but (sadly) can't reply (#lawyerswhippedmyass #asdidMrB). So text/email/DM me if you're a mate. Hope 2 b back soon. xx."
The former Celebrity Big Brother candidate only recently had to deny posting a libellous tweet about Lord McAlpine, the former Tory Treasurer who was falsely linked to child abuse by Twitter users.
Then on Sunday (November 18) she sent a message to her more than 59,000 followers asking what had happened to Jeremy Forrest, the maths teacher who allegedly ran away with one of his pupils.
In the tweet, Bercow also named the teenage girl involved, despite her being protected by a court order.
Journalists who followed her immediately warned her over the mistake, but the tweet was only deleted two hours later. Bercow could now be fined up to £5,000 over contempt of court.
At 2.21am today, the @sallybercow account appeared to have been hacked as a tweet was posted saying: "Hello 1000s of followers (funking lunatics). Stupid woman - password softearev."
Bercow's Twitter account is now offline, although it is unclear whether this was due to legal advice or because of the hack.
But media law expert Sarah Webb urged her to keep the Twitter account switched off for the moment.
"The contempt of court requirements will apply to her just the same as any newspaper or broadcaster," she told the Daily Telegraph.
"I would advise her to be very cautious. I would certainly urge her to turn off her Twitter account at the moment.
"She may not know the law, but equally most people who have an understanding of these things know that in respect of actions involving children and things like that, you can't go around naming them. I think it is surprising that none of these things seem to cross her radar."
Bercow is already facing potential legal action from Lord McAlpine after she got involved in the speculation about allegations a senior Tory was involved in abuse at a North Wales child home.
Earlier in the month, she tweeted: "Why is Lord McAlpine trending? *innocent face*."
A BBC Newsnight documentary had said that a senior Conservative was involved in the abuse scandal, but did not name Lord McAlpine.
However, he was later wrongly linked by some users on the internet.
Lord McAlpine's legal team has said that it will target the people who named him on Twitter, but Bercow has always maintained that the message was "not a libellous tweet - just foolish".
