Your request, as presented, is not logical to me.
Because "certain ignored IDs" are a part of the group, "all ignored IDs".
I suppose the answer is no, but Ill ask again
Is it possible to block public posts from certain ignored IDs without blocking public posts from all ignored IDs?
You wouldn't be trying to put the shuck on me, would ya stranger?
As I often get told, step aside son, you're a blockin' the MOMO!
