I may be able to find one, but honestly, sorry, I don't want to spend 4 hours searching my "unknown finding place". Well, I guess I'll let out my secret.

You can find tons and tons of screenshots in Complaints and Grief reports!
Just look between your join date and your rank-up date. Trust me, you will most likely find one! However, I wasn't able to find one of me because I almost never talked as a Builder. Although, a few of me exist, because I was a Builder for about 3 weeks.

Anyway, good luck if you decide to search :p
