>>5977874The amount of imptrash caught me off guard too, I actually checked a lot of stuff manually because it seemed so high.
Imported threads use the A1 "Anonymous Proxy" flag, same as plain unknown flags. From what I've read Asagi, the scraper archives use, sets these flags to Null by default, so there's no way to search them directly.
I think I'll do /int/ next, they're the next smallest flag board and It should be interesting to see how they differ from us.
