The problem is accounts like this couldn't give a damn about the "quality" of their posts. They are just posting for the sake of what they assume will be easy merits, under the auspices that rank is all that matters when applying for a signature campaign (actual content of posts be damned). It works like this (don't think I'm spilling any secrets anymore):

1. Pick a thread frequented by loose merit sources.
2. Copy/paste something bullish about bitcoin from X.
3. Wait for the merits to trickle in.

Doing any more work than this would render the task above that of "easy money," so that's why they will never do it. They would rather just create a dozen account and have them all flounder at Member status, never actually learning a single thing, except for how to suck up to merit sources more efficiently.
