Why Do Online Forums Require 10 Days And 100 Karma To Post? A Parent’s Guide For Kids New To Niche Communities
It was 9:17 on a Tuesday, and my 13-year-old son was leaning against our kitchen counter, microwave counting down behind him, sighing so loud I could hear him over the dishwasher. He’d spent the last two weeks gluing, sanding, and modifying a custom Lego Millennium Falcon, and he’d just created a new Reddit account to share the build with the r/legostarwars community. When he tapped the post button, a gray error box popped up: In order to post your account must be older than 10 days and have 100 positive karma.
He turned the phone toward me, thumb jabbing at the screen. “What even is karma? Why can’t they just let me post my stuff? It’s not like I’m selling anything.” The microwave beeped, he pulled out his hot pocket, and dropped into a chair at the table, still scowling.
I’d seen that exact error message before, back when I was 16 and joined a gardening forum to share photos of the raised bed I’d built in my parents’ backyard. I got the same rule, same frustration, same urge to just give up and not bother. I pulled out the half-eaten granola bar I’d stashed for my late-night snack and sat down across from him. I didn’t start with a lecture. I just pulled up my own old forum account, still active after almost 20 years, and showed him my first post: a blurry photo of my first tomato plant, half eaten by slugs, with the caption “What am I doing wrong?” Someone commented that I should crush eggshells around the base, that’s still the trick I use every year.
Then I explained what the rule actually means, in terms he could get, not the jargon I’ve seen forum mods use. It’s not about keeping new people out just for the sake of it. Forums that get hundreds of new posts a day don’t have enough mod hours to check every single new account. Bots make thousands of fake accounts a day to post scam links for fake sneakers or crypto, and trolls make new accounts every time they get banned for harassment. This rule weeds almost all of that out before it ever hits the main feed. It’s not arbitrary—it’s the community doing the work to keep the space good for people who actually care about the hobby.
He still thought it was annoying, which was fair. He’d put 15 hours into that Falcon, he wanted to show it off. So we walked through what to do next, step by step. First, I told him not to spam generic “great post!” comments on every thread just to farm upvotes—everyone can spot that, and it usually doesn’t work anyway. Instead, we scrolled through the top posts of the week on the sub, and I had him pick three builds he actually liked, and leave one specific comment each. He told one builder he loved the hidden smoke launcher they’d added in the cargo bay, asked another what specific brick they’d used to get the curved cockpit line, and complimented how another person had weathered their Death Star to look like it had been through a battle. That took 10 minutes.
Over the next week, he checked the sub once a day after finishing homework, and commented on one or two posts a day. He answered a question from another new user asking where to find cheap 32×32 baseplates, linked the Amazon third-party seller he uses. By the morning of day 9, he checked his karma and hit 112.
What surprised me was what we did with the waiting time. He didn’t just sit around being annoyed. I suggested he use those 10 days to tweak his post, and that’s what he did. He retook all his photos in natural light by the window instead of the yellow lamp in his bedroom, added a note about the hidden Han Solo carbonite block he’d tucked in the smuggling compartment that he’d almost forgotten to mention, and read the sub’s rules again to make sure he wasn’t breaking any guidelines.
This isn’t the kind of parenting lesson I plan for. I spend a lot of time worrying about my kid’s online time, limiting TikTok, checking what he’s watching, same as every other parent. But this random internet rule ended up being a better lesson about being part of a community than any lecture I could have given. Most social media these days is built to let you post immediately, chase likes right away, prioritize speed over being intentional. Rules like 10 days and 100 karma force you to slow down, participate first before you take the space to share your own stuff.
For other parents whose kid comes to them frustrated with this same error message, there’s a few small things I found work. First, don’t dismiss their frustration—say “Yeah, that is annoying, I’d be frustrated too” instead of “it’s just a rule, follow it.” Then, explain the purpose simply, don’t overcomplicate it: it stops scams and trolls so people who actually care about the hobby can have a good space. Then, point them toward leaving genuine, specific comments instead of spamming for upvotes—it takes 10 minutes a day, and it works way faster. Finally, suggest they use the waiting time to tweak their post, it gives them something productive to do instead of just moping.
My son posted his Falcon on day 10. He got 78 upvotes, three people asked for the link to his instructions, and another builder gave him a tip for reinforcing the landing gear so it doesn’t sag under the weight. He still complains when he wants to make a new alt account for a gaming sub and hits the same rule. Last week he sighed and rolled his eyes when the error popped up, then grabbed his phone and went to go comment on a few gameplay threads. No fit, no asking me to fix it for him. It’s not a perfect system, and there are still bad actors that get through, but it’s working for us so far. Some of the best lessons are just the random ones you get from an error message, not the ones you plan for.
