Look at https://ask.libreoffice.org/en/users/91483/amarawatt/?sort=reputation. This user had posted something that was marked offensive by several long-time contributors. As a result, the karma had not changed, since it was minimal. However, when the post was deleted by the user, the negative marks were incorrectly "reverted", and user got more than 130 points karma because of that.

Recently cloph had to revert a similar benefit in https://ask.libreoffice.org/en/users/30545/ronzalez/?sort=reputation, so this is an actually exploited and rather bad bug.
