That's the ticket, right there. Uninstall Valheim, then delete steamapps/common/Valheim, and start fresh and clean.

It'll get there. The mods have no issues with moving posts to their appropriate locations; you'll notice the "general discussions" section isn't full of bug reports and "someone play with me" posts, despite those being quite commonly posted in it.

The real problem there is that then the original poster doesn't follow the original post, for some reason, and makes a new post whining about how their post was "deleted"...
