Her latest outburst was last week, after someone criticised her for posting a photo of her grandson, saying she should instead be focusing her attention on floods striking many parts of the country.
"Why is the anger directed at me?" she wrote, saying people should also be asking what the wife of the Jakarta governor was doing as floods engulfed the city.
Last year she was upset when someone posted a comment critical of a picture of her and her family posing on a beach wearing traditional Indonesian "batik" shirts.
The poster said the shirts, considered formal attire, were not the right choice for a day out at the beach.
"Your comment is so stupid," Yudhoyono responded angrily.
Her apology had attracted more than 4000 likes and 300 comments within an hour of it being posted.
She is not the only member of her family active on social media: President Susilo Bambang Yudhoyono regularly posts on Facebook and Twitter, which is wildly popular in Indonesia.
