Not that I care about it much if it is not possible. But it becomes suspicious if merit(s) are sent to posts which clearly are irrelevant and doesn't deserve a merit, so I just wanted to admit an honest mistake.
Fair enough. Don't make it a habit to make those kinds of mistakes and no one will care--everyone makes mistakes now and then, even with merits. I haven't given merits to the wrong post, but I've handed out double what I meant to at least one time for the same post. Just be careful and there won't be any suspicions and you won't be wasting your sMerits.
many users have knowingly gave out huge number of merits to one liners, sometimes 50 merits and above
That happened a lot in the early days of the merit system, and it doesn't happen much anymore (that I know of). Nor were those mistakes. Misuse of merits, maybe. Mistakes, no.
Hmm... I'll take care about it in future. Thanks everyone
