What Is The 10 Day 100 Karma Rule For Online Forums, And What It Teaches Kids About Community
My 13-year-old Lila was slouched over the kitchen island last month, half-eaten cheddar Goldfish scattered next to her Chromebook, when she huffed so loud I looked up from folding laundry. “What’s wrong?” I said. She turned the screen toward me, and there it was: the plain text that thousands of new online community users see every day: In order to post your account must be older than 10 days and have 100 positive karma.
“I made this account yesterday just to ask for a variegated pothos cutting for my swap. Why do they even care how old my account is? Can you just email the mods and tell them I’m not a spammer?” she said, shoving her Chromebook away like it had personally insulted her. I remembered joining that same plant swap forum back when I was deep into houseplants pre-kids, and I’d gotten the exact same message. Back then I thought it was a stupid, unnecessary hoop, and I made a second account to bypass it as fast as I could. I got why Lila was frustrated.
But I didn’t email the mods. Instead, I pulled the forum rules up on my phone, and showed her what karma actually meant on that site: you get it when other users upvote your comments or contributions, and you earn it just for participating, not just for posting your own content. “What if we just try it?” I said. “10 minutes a day for 10 days, that’s nothing. If it’s still stupid after that, we can figure something else out.” She agreed, mostly because she really wanted that cutting.
The first day, she complained the whole time. She scrolled through new posts, groaned that nothing was interesting. Then she saw a 12-year-old kid asking why their monstera had yellow leaves, and Lila had just fixed that exact problem with her own monstera a month before. She typed out a quick comment: “I had this same issue last month! I cut back on watering to once every 10 days and moved it further from the window, that fixed it for me.” Hit post, and 10 minutes later, she got her first upvote. One karma down, 99 to go.
Over the next week, it became a small after-dinner routine. She’d pull out her Chromebook, comment on two or three posts. She complimented someone’s huge indoor fern, agreed with a tip about avoiding tap water for calatheas, shared a link to a cheap propagation tray she’d bought on Amazon that worked for her. By day 8, she had 92 karma. What surprised me was that she wasn’t just doing it for the pothos anymore. She showed me a thread about rooting cuttings in perlite that she’d found, tried the trick on her own extras that weekend, and half of them rooted a week faster than her usual water method. She’d learned something she never would have found if she’d just posted her request and left right away.
On day 10, she got her 100th karma from a mom who thanked her for recommending the propagation tray. She posted her ISO, listed what she had to trade: three golden pothos cuttings and a healthy snake plant pup. Two hours later, a woman 45 minutes away replied saying she wanted the snake plant pup and had exactly the variegated pothos cutting Lila wanted. They did the swap at a local coffee shop the next weekend, and Lila still has that pothos on her bedroom windowsill.
That’s when I started thinking about that rule more. Most people just see it as an anti-spam measure, which it is—scammers and bot accounts don’t stick around for 10 days commenting to earn 100 karma. But it’s also a really quiet, effective lesson about how communities work, that a lot of parents don’t get around to teaching kids about online interaction.
Kids grow up with social media built for instant gratification: you sign up, you post, you get likes within 10 minutes. No waiting, no requirement to give anything before you take something. That means when they join a niche community like a swap group, a homework help forum, or a fan group for their favorite game, their first instinct is to jump in and ask for what they want, instead of hanging out, learning the unwritten norms, and contributing first. This rule forces that slow down, and it’s low-stakes enough that it doesn’t feel like punishment.
The practical thing I’ve started doing with Lila’s younger brother now, when he joins a new online group, is really simple. I don’t fix the rule for him—no emailing mods, no making an account under my name to bypass the wait. If he hits that 10 day/100 karma requirement, we set a timer for 5 minutes a day, and he comments on two existing posts. I point out small unwritten rules he might miss: like that this group doesn’t allow posts asking for free stuff without offering something in trade, or that people here hate when you post selfies unrelated to the topic. That’s something he would have missed if he’d posted on day one, and it saves him from getting the kind of unkind negative feedback that makes kids leave groups feeling bad about themselves.
It’s not a perfect system. Last month, Lila saw a new user get mad about the rule and leave, and she said she wished there was a workaround for kids who just need a quick answer to a question. I don’t disagree. There are also plenty of toxic communities that use arbitrary rules to gatekeep for no good reason, so I still check every group my kids join before they spend time there.
But last week, I saw Lila comment on a new kid’s question about the 10 day rule, explaining how it works, telling him it’s not as bad as it sounds, and that he can DM her if he needs help finding posts to comment on. She didn’t learn that from me. She learned it from waiting, and participating, and seeing how the rule works from the inside. That variegated pothos cutting is still alive, too, growing new leaves every month.
