I wanted to merit a topic that involved a service of exchanging of cryptos between different gambling sites. But mistakenly I sent a merit to a different post which was a reply under the same topic in rush. I would like to know if it can be reversed because I don't want to send a merit to a post that is just a few lines and shouldn't get merit.
https://bitcointalk.org/index.php?topic=5106586.msg49664250#msg49664250 this one is what I wanna reverse. No offence to the OP of that post.

In general too, it would be cool if there was a feature to reverse a merit within 10 mins of sending it.
