Hours after posting heartbreaking tribute to her father, Robin Williams' daughter Zelda announced that she was deleting Twitter and Instragram because of "cruel and unnecessary" comments left by internet trolls.

Tuesday night, Zelda posted and then deleted the following tweet: "Please report @PimpStory @MrGoosebuster. I'm shaking. I can't. Please. Twitter requires a link and I won't open it. Don't either. Please." Both accounts were eventually suspended.

Not long after, she decided to delete Instagram and Twitter from all of her mobile devices.

I'm sorry. I should've risen above. Deleting this from my devices for a good long time, maybe forever. Time will tell. Goodbye. — Zelda Williams (@zeldawilliams) August 13, 2014

Williams elaborated on her Instagram account:

I will be leaving this account for a but while I heal and decide if I'll be deleting it or not. In this difficult time, please try to be respectful of the accounts of myself, my family and my friends. Mining our accounts for photos of dad, or judging me on the number of them is cruel and unnecessary. There are a couple throughout, but the real private moments I shared with him were precious, quiet, and believe it or not, not full of photos or 'selfies'. I shared him with a world where everyone was taking their photo with him, but I was lucky enough to spend time with him without cameras too. That was more than enough, and I'm grateful for what little time I had. My favorite photos of family are framed in my house, not posted on social media, and they 'll remain there. They would've wound up on the news or blogs then, and they certainly would now. That's not what I want for our memories together. Thank you for your respect and understanding in this difficult time. Goodbye. Xo
