The user you are talking about has a bad reputation about loans [defaulted on loan] - check references. But of course you can't blame him for posting something that is considered a big celebration like Eid or so and earns some merit. This is not an abuse of merit, and I don't think it will change his reputation much.
If you take a look at my trust feedback page, you can see clearly that the user which op is talking about is his alt. Op is a newbie one day old account which was created for the reason just a try to debase my reputation.
