CoinGambling.info earned 25 merits for this post. The sender was bitcoincasino.info who has been on the forum for over a decade, and who has never earned any merits or sent any merits other than that transaction. Probably got the merits airdropped when the merit system went into place.

This makes me think:

1. That post does not deserve 25 merits.
2. The two accounts are probably managed by the same person or they are likely people from the same group.

Not that it deserves a red tag but surely a follow-up.
