Creating fake companies and persona is not particularly high effort today, if that's all it takes for a pet project to be featured on Wikipedia, it's going to end up full of crap real quick.

JangaFX, LLC, a North Carolina Limited Liability Company located at PO BOX 27...Wikipedia's philosophy is that it summarizes reliable secondary sources. You're asking for Wikipedia to change its fundamental philosophy so that editors go out and gather primary evidence themselves, debate it, and then deduce what's true by themselves. That would work if Wikipedia were edited by a select group of highly qualified people you can trust, but it's not. It's edited by literally anyone who signs up. So the rules are strict: find a secondary source, or else don't include the info.
I figured bots here were because people maybe were trying out AI tools, scripts, or because keeping their business visible to people who might be interested.
But what benefit can you derive from the Karma.I have pretty good Karma and it hasn't done anything for me that I'm aware of?
"Use reliable secondary sources" is a simple rule that limits the scope for possible conflict and chaos. For an online encyclopedia that anyone can edit, that's very important.
