The zoo deactivated its account on the popular social media platform on Aug. 21 and resumed tweeting @CincinnatiZoo on Tuesday.
Zoo spokeswoman Michelle Curley says the Twitter account went back up last week. It was abandoned following account hacks that targeted the zoo and director Thane Maynor in the wake of Harambe's death.
The Western lowland gorilla was killed by employees after a young boy fell into his enclosure.
Curley says impostors not affiliated with the zoo tried to pass themselves off as the official account during the hiatus. Zoo officials applied to Twitter for verified status.
Based on the replies to the Zoo's new Tweets, it does not look like they are past the Harambe-related social media storm yet.
