I had the trusted rank but now it's member

So about an hour ago I earned the title trusted, and it said I had to reply to a bot or something. But since I wanted to grind instead I didn’t do it immediately. So I check after 30 minutes and now my rank is member. Any idea why?

I don’t think that Trusted is a rank. Your trust level is a member most likely.

Trusted doesnt exist

Firstly there is no ‘trusted’ rank. You also had the basic trust level (TL1) and now you’ve been promoted to the member trust level (TL2) for meeting all the requirements.
