Yes. The requirements for Trust Levels are laid out in the sticky post at the top of the forum. Source for that info is the Discourse softare website, the folks who make the forum software.
TRUST LEVEL 3
Get to trust level 3 by…
- Must have visited at least 50% of last 100 days
- Must have replied to at least 10 different topics
- Of topics created in the last 100 days, must have viewed 500 topics
- Of posts created in the last 100 days, must have read 20,000 posts (both starting posts and replies)

For regular users, even if you are Trust Level 3 on the Overwatch, Heroes of the Storm, or BlizzCon forums, your forum stats and trust level will be different here.
