You don't blame someone for being generous with pure intentions; those who took advantage of generosity are the ones to point fingers at. You might say if the mentioned source doesn't merit those posts, such acts won't continue, but you can't change someone from being good because of the reckless behaviour of others.
From the link shared above, not all of those posts were merited; at least I was able to translate a few, and the one that talked about birthday celebrations was not merited, which shows that Xal0lex doesn't just merit all of them but picks the ones considered to be worthy of merit.
I'm not at all. I just find it funny when posts seem to be given merit when there are so many more deserving posts. If we talk about appreciating & being good, I think it could be just giving 1 merit, not 3, let alone giving 10 merits. It's very inappropriate in my opinion, I also see him as a staff, I don't think it's a good move considering he's someone here.
