This community is for news and discussion about the Kobo line of ebook readers. People come here to talk about Kobo devices, compare them to other e-readers, and share tips or experiences. The rules make clear that general ebook discussion or talk about other e-readers belongs in other subs unless it involves a direct comparison to Kobo.
The rule "Keep it Kobo related" is the first gate. Anything you post must center on Kobo e-readers, and comparisons are fine, but general ebook or e-reader talk belongs elsewhere. The rule "No book promotions, self promo or selling" is the one that will catch most marketers. It bans book promotions, self promotion of apps, extensions, accessories, or anything else, and it makes clear this is not a buy, sell, or trade sub. The rule "No affiliate links" means you must use direct links even for honest recommendations. The rule "DRM & Piracy" allows discussion of DRM removal for legally purchased books but forbids links or names of piracy sites. The rule "Be respectful" rounds things out by requiring you to argue the point, not the person, and follow reddiquette.
A good post here is genuinely about Kobo and nothing else. If you are a founder or marketer, the only way in is to contribute real Kobo knowledge. You might share a tip about using a Kobo device, ask a thoughtful question about Kobo features, or compare Kobo to another e-reader in a way that stays focused on Kobo. If your product is a Kobo accessory, app, or extension, you cannot promote it directly. You would need to participate as a community member first, answer questions, and only mention your product if someone asks and even then without a sales pitch. Direct links are fine, but affiliate links are not, so make sure any link you share is clean.
Avoid any form of self promotion. The rule "No book promotions, self promo or selling" covers books, apps, extensions, accessories, and anything else you might want to push. Do not include affiliate links, because the rule "No affiliate links" says recommendations are great but affiliate links are less trustworthy and lead to spam. Do not link to or name piracy sites, and do not encourage piracy. The rule "DRM & Piracy" allows DRM removal discussion for legally purchased books, but even there you should be cautious about regional legal differences. Avoid posting about other e-readers or general ebook topics unless you are making a direct comparison to Kobo.

No. The rule "No book promotions, self promo or selling" bans self promotion of apps, extensions, accessories, and anything else. General Kobo sales or promotions from retailers are allowed, but your own promotion is not.
No. The rule "No affiliate links" requires you to use direct links instead. Recommendations are welcome, but they must not include affiliate tracking.
Yes, discussion of DRM removal is allowed for books you have purchased legally. However, you must not link to or name sites that distribute pirated material, and you should note that legal requirements for DRM vary by region.
Comparisons are fine as long as Kobo is the focus. General discussions of other e-readers or ebooks are better suited to other subs, per the rule "Keep it Kobo related".
