There's a "bigger picture" that I think you may be overlooking...

Why does a brand new account start posting investigations of alts?

Merits?

Revenge on other users?

Something else?

These brand new / newbies / Jr Members haven't proven themselves in the forum by earning merits the hard way with quality posts, rather, they are posting dubious investigations in the hope of scoring a quick fix of merits.  (some campaigns need as little as five merits in the last 120 days to qualify for participation - earning five through shitty investigations is a gold pass into multiple alts claiming from the same campaign.

Ironic.
