After more than a month away, Robin Williams' daughter Zelda Williams made her quiet return to social media on Monday.

As previously reported, she walked away from Twitter and other social media sites after harassment from Internet trolls over her father's tragic passing in August.

The negative comments she received caused her to ask followers to specifically report several Twitter users. Not long after she decided on the best course of action: ditching social media. She took to Twitter and wrote she was removing social media apps from her phone and may not ever return.

Twitter announced a few days after that they would be reviewing their user-protection policies after learning of Williams' harassment at the hands of a few.

On Monday she simply tweeted, "Thank you," and provided a Tumblr link where she posted a Harvey Fierstein quote.

"Never be bullied into silence. Never allow yourself to be made a victim. Accept no ones definition of your life; define yourself."

Her father passed away on Aug. 11 after dealing with severe depression and was allegedly dealing with the early stages of Parkinson's disease.
