Is the case same here ? Maybe I'm missing on the 'reported many' part,mind linking me to one of those threads where this glitch is actively being discussed ?

I thought the OP sent one merit after the other and just couldn't see it due to page refreshing stuff.Anyway,I don't know if this has been discussed before but I found something interesting while fiddling with the merit input box. https://bitcointalk.org/index.php?topic=3292443.msg34351320#msg34351320
