1/ If you're providing feedback on "spam", it's really helpful if you're precise.

Is the cast:

1. Uninteresting — a "low effort reply", i.e. something that's boring or off-topic

2. Spammy — focused on getting something for free that you're not interested in, etc.

3. Malicious — phishing link, harassment

1/ Work in progress — how to solve low signal content (of which "spam" is a subset).

4 main surfaces in app where low signal content appears:
- Home
- Notifications
- Cast pages
- Channels

"Spam" appears mostly on cast pages and channels. If you have a large audience, notifications.

possibly a banner/icon for new users. 

I see many new users figuring out how to use this platform which leads to making mistake, although not intentional, mentioned above as "problem". 

new user <> give them some benefit of doubt, same mistake/problem continue during longer time frame == ban/shadow
