          Interesting that the bot didn't care about your comments @0x4007 for activity. Also, the `skipBotEvents` didn't seem to work, no rewards have been generated. It is properly set [here](https://github.com/ubiquibot/ubiquibot-config/blob/main/.github/.ubiquibot-config.yml#L34).

The pull-request got merged even though activity was recent (under 2 hours prior), which should have delayed the merge even if CI was green and there was enough validations.
