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.
You do not need to fidget about that, many users have knowingly gave out huge number of merits to one liners, sometimes 50 merits and above, so it really doesn't matter and you needn't make a thread to exonerate yourself.
Theymos doesn't want strict moderation on how merits are handed out, so there is a slim chance of getting into trouble on how you use your Smerits, unless of course it's proven you send merits to alt accounts.
If you have more Smerits, you can go ahead and merit the post you originally intended to merit.
