The trust levels in Discourse are all handled automatically based on contributions to the forum over time -
To get to trust level 3 (Silver), in the last 100 days…
- Must have visited at least 50% of days
- Must have replied to at least 10 different non-PM topics
- Of topics created in the last 100 days, must have viewed 25% (capped at 500)
- Of posts created in the last 100 days, must have read 25% (capped at 20k)
- Must have received 20 likes, and given 30 likes.*
- Must not have received more than 5 spam or offensive flags (with unique posts and unique users for each, confirmed by a moderator)
- Must not have been suspended or silenced in the last 6 months
* These likes must be across a minimum number of different users (1/5 the number), across a minimum number of different days (1/4 the number). Likes cannot be from PMs.
All of the above criteria must be true to achieve trust level 3. Furthermore, unlike other trust levels, you can lose trust level 3 status . If you dip below these requirements in the last 100 days, you will be demoted back to Member. However, in order to avoid constant promotion/demotion situations, there is a 2-week grace period immediately after gaining Trust Level 3 during which you will not be demoted.
