I'm only new here. I wasn't hiding that I was looking for information to make sleeves. That's what I make. [...] But yeah, you guys are pretty agro [...] Let's be honest, it hasn't been a smooth ride.
In general, this whole forum is mostly a community site, not a sales venue, and many of the members here don’t really want to mix too much commercialization into the fabric of the forum, because it’s seen to cheapen the culture of the community. There are specific subforums for selling stuff (under the “geekhack marketplace” section), and advertisements/commercial activity mostly stays contained there. If you had made a post advertising your sleeves under the “artisan services” subforum, you’d have no problem. Alternately, in the “keyboards” subforum there’s a thread called “simple questions, simple answers” which is a great place for one-line questions like yours.
“Making stuff together”, however, is a subforum mostly devoted to people’s construction process, and documenting and sharing advice about stuff we’ve made, for others to learn from. If you browse through the posts here, you’ll see people have put an incredible amount of effort into sharing their deep knowledge, with how-to guides on restoring old keyboards, reverse engineering old keyboard protocols, modding keyboards to include new features, building new cases for old boards, building brand new keyboards from scratch, molding custom-shaped keycaps, producing wrist rests in various materials, sleeving cables, etc. etc.
I suspect you can figure out how if a newcomer with no history or reputation posts a lazy question with an advertising-y link to a commercial website here, it might turn people off. It’s similar to the response you get if you go to a scientists’ forum and you ask how to do your undergrad homework problem.
