What the 10-day, 100 positive karma posting rule teaches kids about joining online communities
I was folding the week’s soccer uniforms last Tuesday when my 13-year-old son Javi slammed his phone face-down on the coffee table hard enough to rattle my half-empty iced tea. “Stupid. Why won’t they just let me post?” he said. I looked up, wiped grass stain off a sock, and asked what he was trying to share. He’d spent six weeks scrolling the r/PlantTrade subreddit, checking every other day for a local seller offering a small variegated pothos cutting—his white whale, the plant he’d saved $40 of allowance to buy. That night he’d finally found one, listed for $10 15 minutes from our house. When he hit “comment” to claim it, a box popped up with the line we’ve all seen if we’ve ever joined a new online community: In order to post your account must be older than 10 days and have 100 positive karma.
Javi had made the account three days earlier. He’d never heard of karma. He thought it was some kind of paid membership, or a trick to keep new people out. I sat down next to him and pulled up the subreddit rules on my own phone to show him. The rule wasn’t arbitrary, I explained. Most trading and hobby groups use rules like this to block scammers and spam bots, which almost always use brand-new accounts. Karma is just the number of upvotes other users have given your comments and posts—proof you’re a real person who’s participated in the group, not someone here to steal money or post fake links.
Javi didn’t care about scammers. He cared that he’d waited six weeks for this cutting, and now he had to wait 10 more days, and he had no idea how to get 100 karma fast. He argued that it was unfair—he wasn’t a scammer, so why should he be punished? I get that frustration. I’ve been locked out of posting in new groups myself, and it’s annoying when you just want to join in. But I didn’t offer to let him use my account to claim the cutting, or message the mods to beg for an exception. I’d seen too many parents step in to fix every small inconvenience for their kids online, and I knew this was a better lesson than any I could plan.
I asked him what he knew that other people in the group didn’t. He’s been growing houseplants for two years, he’s propagated more than 30 cuttings, he’s fixed root rot in half a dozen struggling plants that I was ready to throw out. I suggested he spend 10 minutes a day scrolling the new posts page, and answer one question a day from new plant parents who needed help. No generic “good luck” comments—specific answers, like what kind of soil to use for pothos, or how to tell if your plant is overwatered.
He grumbled, but he had no other plan, so he started that night. By the end of the first day, he had 14 upvotes. By day five, he had 62. By day nine, he hit 98. He was so close, he checked his phone between classes that day, refreshing every hour. That evening, we saw the seller had marked the cutting as sold—someone with an older account had claimed it 24 hours before Javi’s account hit the requirements. He was disappointed, moped through dinner, and said the whole rule was garbage. I agreed it sucked that he missed out, and left it at that.
A week later, another local seller posted the exact cutting he wanted. Javi had 127 positive karma by then, his account was 17 days old, he commented right away, and he brought the cutting home two days after that. What surprised both of us was that he’d already made a small connection in the group from answering questions. One new plant owner he’d helped with root rot DMed him a few days before to ask for more advice, and they ended up trading a snake plant cutting for one of Javi’s extra pothos. He told me last weekend he never would have talked to that person if he hadn’t had to work for his karma.
Most of the conversations we have about kids online are about safety, screen time, or bullying. We rarely talk about these small, unspoken rules of community membership that kids run into every day. The 10-day, 100 karma rule isn’t just a platform technicality—it’s a clear, concrete example of how any community works, online or off. You don’t walk into a new club at school and ask for a favor from the group before you’ve said hello to anyone. You don’t join a local gardening swap and take a plant before you’ve spent any time getting to know the group. That’s what this rule teaches, plain and simple.
For parents who run into this same situation with their kid, the steps are simple. First, explain what the rule is actually for—not that it’s punishing your kid, just that it’s filtering out people who don’t actually care about the group. Second, don’t fix it for them. Don’t use your account to post for them, don’t pay for fake upvotes, don’t badger mods to make an exception. Third, help them brainstorm 2-3 small, specific contributions they can make in 10 minutes a day to build up karma, based on what they already know. It doesn’t take big posts to get upvotes—helpful answers, specific compliments on other people’s work, that’s all it takes.
Javi still gets frustrated when he makes a new account for a different hobby and hits the same rule. Last week he wanted to vent about his math teacher in a teen gaming group, and his new account was too new to post, so he ended up venting to me over tacos instead. That wasn’t the worst outcome. He still says the 100 karma rule is dumb more often than not, but he now knows it’s just how the group works. I don’t think one small incident like this makes anyone a perfect digital citizen, but it’s the kind of small, lived lesson that sticks longer than any lecture I could give. Right now, he’s got his new pothos on his windowsill, and he’s answering a root rot question as I write this. That’s enough for me.
