Another passenger onboard the cruise ship "Allure of the Seas" saw the woman standing on a narrow ledge on the outboard side of a balcony rail, her hands above her head. The fellow passenger thought that the woman may have intended to go overboard and thus, reported the incident to the crew.

Peter Blosic reported to CNN that while he was standing at his balcony, he saw a woman climbing on her railing; Since he had no knowledge of the woman's intentions, he alerted the crew.

If I said nothing, and she was going to jump, that would be horrible

... Mr Blosic added.

Following the alerts, the crew found the woman and removed her from the ship at the next port call in Falmouth, Jamaica.

The cruise company issued a statement according to which

Earlier this week on the Allure of the Seas, a guest was observed recklessly and dangerously posing for a photo by standing on her stateroom balcony railing with the help of her companion. Security was notified and the guests were later [disembarked] in Falmouth, Jamaica as a result of their actions and are now banned for life from sailing with Royal Caribbean.

This is not the first time that the cruise company has banned a passenger; Specifically, in early 2019, a  27-year-old man and his friends were banned for life from travelling on Royal Caribbean's cruise ships, after he was shown jumping overboard from the 9th deck of 'Symphony of the Seas', the world's largest cruise ship to date.

In light of the severity of the situation and in boosting the existent safety measures, the USCG announced in September that high-risk-behaviour passengers are to be fined with up to $34,000, according to specific criteria.
