The letter by Brockell was published this week by The Washington Post, where she works as a video editor.

Brockell, who declined to comment for this article, noted in her letter that social media platforms should be able to detect from her online activity that she did not deliver a healthy baby.

“But didn’t you also see me googling “braxton hicks vs. preterm labor” and “baby not moving”? Did you not see my three days of social media silence, uncommon for a high-frequency user like me?” she wrote. “And then the announcement post with keywords like “heartbroken” and “problem” and “stillborn” and the 200 teardrop emoticons from my friends? Is that not something you could track?”

Brockell’s letter has been shared on Twitter more than 25,000 times. Many of the commenters shared similar experiences.

“I received big envelopes and packages in the mail from Shutterfly on my baby’s due date and for many months, encouraging me to capture memories of the first year. I had miscarried at 12 weeks and I never signed up for Shutterfly. So sorry for your loss,” wrote one commenter.

“Heartbreaking. I lost four pregnancies (although thankfully all much earlier) so I absolutely understand exactly how horrific these posts can be. So sorry and wishing you all the best in persuading them to tackle this,” wrote another.

Brockell also received a tweet in reply to her post from Rob Goldman, the vice president of ads for Facebook, who said the platform is working on the issue.

Goldman shared that there is a way to change ad settings manually on Facebook, by going to Settings>Ad Preferences>Hide ad topics.

I am so sorry for your loss and your painful experience with our products. We have a setting available that can block ads about some topics people may find painful - including parenting. It still needs improvement, but please know that we’re working on it & welcome your feedback.

Brockell said in a later tweet that once she adjusted her ad settings on Facebook, she received an ad about adoption.

And here's a look at how effective it is when you finally do find the corner of Facebook where you can turn off parenting ads. Just came up in my feed. (And no, I have not been googling about adoption. I am miles away from anything but grieving.) cc @robjective pic.twitter.com/bHxcPIoYfW

Facebook and Instagram, which is owned by Facebook, did not reply to requests for comment.

\"We cannot imagine the pain of those who have experienced this type of loss,” a spokesperson for Twitter told \"GMA\" in a statement. “We are continuously working on improving our advertising products to ensure they serve appropriate content to the people who use our services.\"
