Trust Level 3?

[Lejk-nagrand (Lejk)]

Stolen from a green in the Level 3 Lounge.

To maintain trust level 3 you simply need to make sure that at any given time you fulfill the conditions of trust level 3.

• 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)
• 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) (If this happens it simply resets your stats back to zero and you have to rebuild)
• Must not have been suspended (including forum suspensions or in-game account actions of any Blizzard game) (If this happens it simply resets your stats back to zero and you have to rebuild)

So apparently you can earn it back.

You also need to maintain all of the above over a 100 day period to keep your Level 3 status active.
