It's Jinger Duggar who has a reputation as her family's resident rebel, but Jana is a bit of a rulebreaker in her own right.
For instance, Jana has an Instagram account, making her the first unattached Duggar to join social media.
Usually, Duggar kids are forbidden to join the world of selfies and hot takes until after they've entered a courtship.
But Jana said nuts to all that and hopped on the 'Gram last year.
Insiders say she didn't receive much resistance from her parents, which makes sense.
After all, Jana is 30 now, and incidents of Instagram users being tricked into worshipping Satan because their husbands weren't there to intervene are reportedly quite low.
Not only that, the Duggars aren't as well-off as they used to be, and Jana has earning potential that she can't take advantage of just sitting at home.
These days, it seems that Jana is launching a one-woman media empire.
The goal is to rebrand herself as a sort of evangelical lifestyle guru -- a Martha Stewart for the fundamentalist set.
Jana is following a blueprint that's been used effectively by other top influencers, and she's currently uploading a lot of original content to YouTube and using her Instagram page to promote the channel.
The problem is, a lot of her followers aren't very bright, so when Jana links to her YouTube channel from Instagram, they think she's promoting sponsored content from a third party.
“Just posted a new video on my YouTube channel! Simple steps and how I do my own gel nails at home! The link is in my bio," Jana recently posted.
“Jana, love your posts and craftiness video, but not the paid commercials on gel nails …” one fan replied, seemingly missing the point.
Jana generally isn't the combative type, but in this case, she was quick to set the record straight.
“It’s not a paid commercial or ad. It’s something I bought myself and have really enjoyed using! Just wanted to share something I found helpful with you all!” she wrote.
Jana kept it civil, but the fan did that common social media thing where she admitted to being in the wrong, but then continued to defend herself.
“Well, that is different then,” she wrote, “but many reality stars are ruining their pages by all the paid ads.”
So basically, You didn't do the thing I accused you of, but other people have done it in the past, so I'm not wrong.
Sigh. We live in very normal times.
This is the internet in 2020, so the situation escalated from there, with some fans going so far as to bring up the feud between Derick Dillard and Jim Bob Duggar -- specifically, Dericl's allegation that Jim Bob pockets his kids' earnings.
“Papa really must withhold TLC income for the kids if y’all have to sponsor [yourselves out]!” the follower wrote.
Not surprisingly, Jana opted not to reply to that one.
