IAmAs Should NOT Be About:

• Your experiences on the internet.

• Something previously posted multiple times, or common topics.

• Your day, your girlfriend, being bored or drunk, your opinion on something, etc.

• Stories about fetishes, abuse, drugs, relationships, or mental disorders are too common
