(bug): block does not work in groups

Summary

If user A blocks user B, user B will still appear in the group-feed of user A.

Steps to reproduce

Unknown - it appears to happen rarely, but very randomly.

I have seen multiple reports and I and other team members have seen it happen first-hand.

Platform information

Cross-platform web.

What is the current bug behavior?

Blocked users show up in feeds.

What is the expected correct behavior?

Blocked users should not appear for the blocker.

Relevant logs and/or screenshots

(Paste any relevant logs - please use code blocks (```) to format console output, logs, and code as it's very hard to read otherwise.)

Possible fixes

Let's make sure

• Banned users disappear from the UI on feeds
• Banned users do not appear on reload
• We need to make sure that admins can only see blocked users by explicitly going to their channel page. They should not be showing up in anyone's feeds.
