# Discovery & community

Discover is Koo's public gallery: every app with a published [app page](/docs/showcase/app-pages) shows up there, and anyone can browse it — no sign-in required. The community layer on top — upvotes, comments, follows — requires a Koo account.

## Browse Discover

Three controls shape what you see:

- 
- 
-

Results load as a continuous list; keep scrolling to see more.

## Upvote apps

Upvote an app from its public page or its Discover card.

## Comments

You can comment on any public app page. Threads allow one level of replies: you can reply to a top-level comment, but not to a reply, which keeps discussions flat and readable.

Other accounts can vote each comment up or down, and comment activity counts toward an app's ranking signals.

> **Note:**
>
> You comment as your **selected account**. If you belong to more than one account — a personal account and a team account, say — check which one is active before posting; the comment is attributed to that account's handle and [profile](/docs/showcase/your-profile).

## Follow makers

Follow an account from its profile or from any of its app pages to keep up with what it ships. Follows are public: they count toward the account's follower total shown on its profile.

Like comments and upvotes, you follow as your selected account, and you can unfollow at any time.

## Reporting & moderation

If you see content that crosses the line — spam, abuse, anything that violates Koo's terms — report it. Comments, app pages, and profiles can all be reported; pick a reason and optionally add detail. Reports go to Koo's moderation team for review.

When moderation removes content, or its author deletes their account, the content is replaced in place with a `[deleted]` placeholder rather than erased. Replies and vote counts stay intact, so threads remain readable.

## Community expectations

Be respectful, be honest about what you ship, and keep it lawful — the full rules live in [Koo's terms and acceptable-use policy](https://koo.io/legal).
