## What The Pillar is

The Pillar is a browser game and advertising marketplace. A window is a licensed ad pane on a 3D tower, not real property and not a security.

This page is a plain-language summary for players and advertisers. It is not legal advice, and a window on The Pillar is not real estate and not an investment.

## Marks and links

The logo, name, and link on your window must be yours to use. Do not upload marks you do not have rights to, and do not link to malware or illegal material.

Absolutely no child sexual abuse material. No content that is illegal where The Pillar operates.

## Identity and chat

Do not impersonate another person, brand, or The Pillar itself. Keep the lobby chat free of harassment, spam, and illegal content.

We may remove a mark, dim a window, or suspend an account that breaks these rules.
