If this kind of thing happens again, use this: https://bitcointalk.org/index.php?action=trust;full;dt

And search for that username on the page (Ctrl-F or whatever).

Edit: you're using a custom trust list so perhaps olcaytu2005 wasn't even on DT... use the link without "dt" then: https://bitcointalk.org/index.php?action=trust;full
