Why Kids Can’t Post in Most Reddit Hobby Groups: A Parent’s Guide to 10-Day and Karma Rules
Last Tuesday, I was scraping leftover penne into a container after dinner when my 13-year-old, Jax, slammed his phone down on the table hard enough to slosh my iced tea. He’d spent three weeks and $42 of his allowance building a custom Lego AT-AT that converts into a hidden speeder garage, and he was desperate to share it with the 200,000-member Lego Star Wars fan group on Reddit he’d been scrolling for months. I leaned over to read the message glowing on his smudged cheese-stained screen: In order to post your account must be older than 10 days and have 100 positive karma.
I had no clue what positive karma even was. I use Reddit exactly once a year to look up a crockpot chili recipe, so all that jargon might as well have been Klingon. Jax sighed, dramatic as only 13 can be, and explained that karma is just points other users give you when they like your comments or posts. He’d made his account that very morning, because he didn’t want to post his Lego on my old account that only has comments about school fundraiser pickups. Now he was stuck.
My first reaction was to snort and say that sounded like a dumb, arbitrary rule. Why keep a kid who just wants to share his hobby out just because his account is new? Jax nodded so hard his hoodie slipped over his eyes, and started listing all the reasons it’s unfair: he’s not a scammer, he didn’t do anything wrong, why should he have to jump through hoops just to show people his work. My 8-year-old stole half his garlic bread while he ranted, and he didn’t even notice.
I sat down next to him instead of walking away to clean the kitchen, like I almost did. I’ve learned over the years that the things that feel tiny to adults are almost never tiny to kids. I asked him what he’d read about why the rule exists. He mumbled that it’s to stop bots and scammers, but that didn’t make it less annoying. So we pulled up the group’s removed post log together, just out of curiosity. Over the last 24 hours, 17 posts had been removed before they even went public. Fourteen of them were from new accounts less than a day old, linking to fake “free Lego” giveaways that steal credit card info, or spam for knockoff toys that break after a week. Jax scrolled through them, quiet for a minute, then said “Oh. I didn’t realize there were that many.”
That’s when it clicked for me that this random internet rule isn’t just gatekeeping. It’s a lesson about how communities work, if you take two minutes to walk through it with your kid. A lot of parents I know either brush off their kid’s frustration (“It’s just the internet, wait a week”) or try to cheat the system (“I’ll just let you post it from my account”). Both of those miss the point. I’ve got three concrete things I did that worked, that other parents can steal next time their kid runs into this.
First, I started by validating the frustration before I started explaining the rule. I said, “It does suck. You worked three weeks on this, and you just want to show it off. I’d be annoyed too.” That’s way more useful than jumping into “well actually it’s a good rule” right away. Jax stopped slouching and talking through his hoodie after that, because he didn’t feel like I was on the rule’s side against him.
Second, I helped him figure out small, low-effort ways to earn karma that don’t involve spamming or being fake. The myth I’ve heard is that you have to post your own content to get karma, but that’s not true for most hobby groups full of kids. We went through the new feed that night, and I helped him leave specific, nice comments on other people’s builds. He commented on a kid’s custom Millennium Falcon that the way they did the landing ramp was genius, because he’d been stuck on that same problem for his own MOC. That got three upvotes in an hour. The next day, he asked a question in a thread about where people buy rare used bricks, and got another seven upvotes from people who shared their favorite sites. By day 8, he had 112 positive karma. He still had two days to wait before he could post, but he stopped complaining after that, because he was already talking to other kids about Lego.
Third, I connected the rule to things he already gets offline. I said, “Remember when you joined the new Minecraft server at school? You couldn’t just start a new base right in the middle of the town everyone already built. You had to hang out, help people gather resources, and ask where you could build before you put your own thing up. This is the same thing. It’s not just for scammers, it’s for people who join just to promote their own stuff and never help anyone else out.” He rolled his eyes, but he nodded, because he remembered that kid who joined the server and spawned a bunch of TNT in the middle of the community town, so he gets bad actors ruining it for everyone.
His 10 days were up last Saturday. He posted his AT-AT right after breakfast, and by dinner it had 218 upvotes, and 12 people asked him for instructions. He’s been trading part lists with three other kids who want to build their own convertible AT-ATs all week. He still says the 10-day rule is dumber than the school’s no-chip rule, but he also admitted that getting to comment on other people’s builds first let him find a few people who like the same weird custom Lego stuff he does.
I still don’t totally understand why karma works the way it does, or why some groups have stricter rules than others. Next time Jax joins a new group, he’ll probably still get frustrated when he runs into the same requirement. But I’m not in a hurry to fix it for him anymore. These random, annoying online rules turn out to be good practice for being part of any community, online or off. It’s just a matter of stopping long enough to walk through it with them, instead of brushing it off as another weird internet thing.
