Sorry I kind of got confused. As I recall Lauda was a staff so I though that it is autmatic to be listed in DT1 but I guess my understanding is wrong. But I think he should still be a DT member since he displayed a good combat against spammers but if not then it is fine since he holds a number of campaigns hence he can still do it.
Combatting spammers shouldn't count for anything to do with DT. The moderators / admins should be taking action against spammers.
Lauda was active against scammers. Has somebody else in DT tagged the accounts which Lauda had previously tagged?
