Seems a bit glitchy - as <10 characters aren't tracked on the data I wasn't expecting to find anything on it, but it seems my lvl 5 alt is getting picked up off the guild roster? I haven't logged it in since dinging 5 anyway, which was some time ago, but it's in the same guild as my more active alts. Also from the number of times it's listed, I'm guessing the database thinks it's a new update every time I submit, perhaps due to interaction with the <10 characters not being shown?
Also this character (and all the other <10 ones in the guild) shows on the guild ex-members list - they're still in the guild, so maybe better for the ex-members list to just ignore <10 characters, if they can't be included on the roster? The <10 restrictions were in place well before I ever joined that guild too, so it's not a holdover from past days!
Interestingly looking at it, it seems that any <10 characters in a guild where someone censuses do get their own entries in the database, but others don't, as I can't find my unguilded bank alts, but all the <10 in this guild are findable on the site, even if I've never seen them online.
