For the most part, the reality stars we love to watch on TV seem to live happy lives, and enjoy support from their devoted fans.
But, like all celebrities, they also face huge numbers of online trolls, who make a habit of posting mean things to get a rise out of public figures and their fans.
One of the most common types of these commenters are "mom-shamers," parents who decide they know how to raise children better than the women they shame on social media - either out of genuine concern or just plain nastiness.
Tori Roloff, the star of the hit TLC reality series Little People, Big World, revealed this week that she's fed up with those kinds of comments.
In an honest and emotional Instagram post this weekend, the reality star sounded much wiser than her 27 years as she told fans to be kind.
"Mom shaming is a real thing and it's not cool," the young mother wrote.
"I get it all the time because I put my tactics out there and I try to be as honest about my life as possible.
"But for some reason lately I've been getting a lot of people bashing my momisms or how I do things in my home. I don't want my social media to go there."
Tori, who often shares photos of her husband Zach and their newborn baby Jackson, admitted that her family isn't perfect, but also reminded fans to "judge not, lest ye be judged."
After all, she wrote, "There are people behind your screens and you never know what a person is walking through."
"My life is far from perfect. I know that and I'm okay with that. But when moms and sisters and friends and whoever start shaming each other for what they do with their kids that's where I draw my line."
While her post resonated with a number of mothers, and comments poured in to cheer Tori on, she made it clear that she was not fishing for compliments.
"I didn't post this for people to tell me I'm a good mom," she wrote. "I'm the best one I know how to be. I posted as just a reminder to EVERYONE to lift one another up. Don't knock each other down."
It's not the first time that Tori has taught her fans a lesson about rude social media behavior.
In October, fans convinced they spotted a "baby bump" on Tori in a video shared by Zach's father, Matt, posted a deluge of comments asking if she was pregnant.
"No, I am not pregnant," Tori replied. "Yes, I love baggy clothes and food."
She went on to scold her followers for fueling pregnancy rumors that could be seriously hurtful to parents, especially ones struggling with infertility.
"What if I was a woman who couldn't get pregnant? What if I was a [woman] who had body image issues?" she asked.
"Asking a woman if she's pregnant can be extremely damaging."
While Tori realizes her fans are asking "from a place of love," she wants them to "think twice" before asking women if they're expecting.
"You don't know what's going on behind closed doors in anyone's life."
Tori's sister-in-law, Audrey, has had to fend off all the same rumors and gossip, including when fans speculated she was expecting a second child with her husband, Jeremy, just ten months after their daughter Ember was born.
"This kind of stuff just makes me realize how much fake news is out there," she told fans.
"Again, if you didn't hear it from my mouth...It's probably not true."
