is there a thread anywhere where we keep track of users who constantly write posts just to reach the minimum quota required by signatures campaigns?
No, but there is a similar thread ehich is about users who spread false/fake/unhelpful information but on on technical boards.
https://bitcointalk.org/index.php?topic=5550099.msg65585513#msg65585513You can begin another one which is about discussion on all boards on this forum. Or just make it different by saying it is about fulfilling weekly posts.
But almost all posters on this forum posting on threads that is more than two pages long are doing that. Not all of them but almost all of them.
