About "prohibited acts" and "cautions"

<About prohibited acts and precautions on IRIAM>

In order for users to use IRIAM with peace of mind, please be careful of the following actions in all situations, including "broadcasts", "comments", and "posted content".

If we find any content that violates the membership terms, individual contracts, or other rules specified by our company, we will issue a warning or freeze your account.

This page summarizes "examples" of prohibited acts and precautions on IRIAM.

In addition, as a basic premise, the impression given by an expression is comprehensive, and we will not judge the review based only on individual partial expressions.

Furthermore, when it comes to IRIAM's live streamers, they are perceived as "fictional character expressions, but also living beings", so the standards tend to be stricter than fictional character expressions that are considered to be completely fictional. We would appreciate your understanding on this point.

In addition to taking into account the actions and precautions discussed on this page, please consider the feelings of other live streamers and listeners and abide by the membership terms and manners when using the service.

We have provided links for each item, so please check the links for more details.
