**Abuse is a very real problem on Session. Make sure to appoint sufficient moderators to your Communities**.
Communities listed on our site must take care to [follow our policy](README.md#policy), which includes the [Session Terms of Service](https://getsession.org/terms-of-service).
## Diagnosing listing issues
If your Community does not appear on our list:
- first, confirm it is listed on an upstream source,
- verify it can be joined from the app,
- check in our page footer that the list has been updated recently, and
- ensure your Community [follows our policy](README.md#policy).
If your Community still does not appear on our list, [please contact us](README.md#contact-us). Note that poor connectivity may affect our ability to list Communities in regions affected by internet censorship.
Due to the lack of progress on the [issue of built-in Community tags](https://github.com/oxen-io/session-pysogs/issues/187), you may instead insert tags at the end of your room description like so:
The obvious benefit is searchability. However, tags such `#nsfw` or `#test` also help us automatically hide parts of the Community display:
The `#nsfw` tag hides the Community avatar and ensures visitors know your Community is not safe for work, while the `#test` tag marks a Community as "intended for testing" and hides it from our index. The `#unlisted` tag can be used for the same purpose, such as when archiving Communities.
You may notice the Host column groups Communities by their host SOGS, and some SOGS are easily recognizable by a unified icon. If you also want your Communities to be linked by a recognizable icon, the requirements are easy:
- The icon must be the same as an existing Community avatar.
- The icon must be safe-for-work, i.e., no suggestive or violent material.
- Your Communities must take care to [follow our policy](README.md#policy).
Once you've chosen which of your existing Communities will share an avatar with your whole server, [contact us](README.md#contact-us).
## De-listing requests
We occasionally accept requests from server operators to de-list whole Community servers.
If you feel our listing would be detrimental to your Communities — such as in cases where your Communities reveal sensitive information about your users — you may [contact us](README.md#contact-us) to request to de-list a Community server. Please note that Session Communities are not designed with private communication in mind.
