I realize I've mentioned it before, but I now run into it weekly so out of self-interest I'm posting a request:
Can BPIP re-check all userIDs it didn't index? I use BPIP to get userIDs for the usernames in theymos' Trust data dump, and just this week, 3 usernames (and userIDs) are missing from BPIP (which means I have to manually add them to update my Trust list viewer):
TYCOON_officialGOLD_officialusernetwork7248My estimate is that at least a few tens of thousands of userIDs are missing. If you can check which (consecutive) userIDs are missing in your database, you can scrape those profiles to update them.
