Good catch! I saw the campaign ran by a Newbie, and was happily surprised to see a green trusted user involved as escrow. Well, that didn't last

I also noticed a small army of high ranking users (with 0 earned Merit) that suddenly activated to join this campaign. About half of them were last active on January 13/14, the other half wasn't active for a few months.
I refuse to believe they all by coincidence saw this thread at the same time, so I'm pretty sure many of them are controlled by the same user.

For reference: thread archived.
These users have posted in that thread ("0 Merit earned" means they have sent Merit, if nothing is mentioned they've neither sent nor received Merit):
