I'm looking at the vbseo_linkback table trying to figure out which field controls the "thread not found" indicator that we see when moderating old linkbacks in the vb admincp. I'd like to be able to delete via a mysql query those old linkbacks that no longer exist (but were previously approved).

I thought it might be the t_deleted field which shows either "1" or "0" but it doesn't seem to have a 1:1 correspondence with those linkbacks showing as "thread not found" in the admincp.

Could someone advise which table/field controls this and how?

Thanks. -- Rik
