What ’10 days old and 100 positive karma’ posting rules mean for kids’ online groups: A parent’s guide
I was folding grass-stained soccer hoodies at the coffee table last Tuesday when my 13-year-old, Lila, threw her phone onto the cushion next to me with a dramatic huff. “This is so stupid,” she said. “I just want to post my pothos cuttings for trade and they won’t let me.” I wiped a stray crumb of granola bar off my jeans and leaned over to see the error message blaring on her screen: In order to post your account must be older than 10 days and have 100 positive karma.
Lila had been following that teen plant swap group for six weeks, waiting until she had enough extra cuttings to trade for the variegated string of pearls she’d had her eye on. She’d made the account the night before, snapped bright photos of her healthy, rooted pothos, and was ready to go. This rule felt like a random, unnecessary roadblock to her. I get that. When I first saw messages like this a few years ago, I thought the same thing—just gatekeeping for no reason, right? But back when my oldest was a toddler, I spent two years modding a local parent activity group on Reddit, so I’ve seen exactly why these rules exist.
Back then, we got 10 to 15 new joiners a day, and at least half of them were spam or fake accounts. They’d make an account the same day they joined, immediately post links to fake giveaways, adult content, or scam ads for overpriced baby gear that never showed up. Trolls would make throwaway accounts to call other people names, share someone’s personal info after a disagreement, or start fights then delete the account before we could ban them. We tried all kinds of fixes: manual approval for every new post, keyword filters, even a question new people had to answer to join. Nothing worked as well as when we added that exact same rule: 10 days old, 100 positive karma, before you can make a new post. It cut our spam and trolling by 80% overnight.
I explained that to Lila. She rolled her eyes at first and said, “I’m not a troll, why do I have to wait?” That’s fair. When your kid is excited about a hobby, any delay feels unfair. My first instinct was to fix it for her immediately: I have an old Reddit account that’s been around since 2012, has thousands of positive karma. I could just let her post from my account, get the whole thing over with in five minutes. But then I stopped. First, that group is specifically for teen gardeners, and most mods ban posts from adults outside the age group anyway. Second, bypassing the rule meant we’d miss a low-stakes chance to talk about how online communities actually work, something I’ve been trying to teach Lila gradually instead of just handing her a phone and saying “be safe.”
We sat there for 10 minutes, scrolling through the group feed together. I explained that karma isn’t some fancy popularity contest. It just means other members liked your comment enough to upvote it, which signals to the group and mods that you’re a real person who’s actually participating, not just here to sell something or cause trouble. Instead of waiting around doing nothing, we picked out 15 posts she actually cared about to comment on. She told a girl with a windowsill full of succulents that her own succulents always die within a month and she loved the setup, asked another person how they got their pothos to grow so fast, complimented someone’s hand-painted custom plant pot. That took 20 minutes, and we did a couple more comments every other day when she was scrolling anyway.
As a parent, I see so much vague advice online about teaching online safety—most of it boils down to “don’t talk to strangers” and “limit screen time.” But this random-sounding rule is a built-in safety feature that most parents don’t even stop to explain. The 10-day wait stops anyone from making an account just to cause trouble and dipping right after before they can be held accountable. The 100 karma requirement means scammers and trolls can’t just post and run; they have to interact positively first, which most of them won’t bother doing. It’s low effort for volunteer mods who run most kid-focused hobby groups, and it works way better than any fancy automated filter I’ve seen.
For other parents who run into this rule with their kid, the steps are straightforward, no extra work required. First, don’t jump to bypass the rule with your old, established account. It’s fine if you’re just popping in to check one thing, but if your kid wants to be an active member of the group, let them go through the process. Second, sit down for five minutes and explain what the rule actually means—most kids have never heard of karma, so they just assume it’s a stupid website rule for no reason. Third, help them leave a few genuine comments on posts they care about to get started, instead of just leaving them frustrated. It doesn’t take long, and it’s a quiet way to practice kind, intentional online interaction before they start posting their own content.
Right now, we’re at day 8. Lila hit 112 positive karma two days ago, and she’s just counting down the two more days until she can post. She’s still a little annoyed that she had to wait, but she also got a free tip from another group member about rooting cuttings in perlite instead of water, which she’s already testing on her windowsill. Tomorrow we’ll post the pothos photos, and we’ll see if anyone wants to trade for that string of pearls. I don’t know if it’ll work out, but this whole thing was a better lesson about online communities than any of the awkward talks I’ve given about screen time. Some of those weird-sounding website rules aren’t just random hoops. They’re there to keep kids safe, and they turn out to be pretty good teaching moments too. We’ll see how the trade goes.
