Hi Jansi,
Sorry about the late reply!
I really appreciate the integrity, but I would suggest to keep the badge and points if you are okay to accept that. The reason as the time we speak you've already made valid progress towards the badge, and you will lose that if I remove the badge. So we usually do that to really invalid content.
I can however remove the 30 points for the repeated creation of the blogs. I will do that after your confirmation.
Best,
Sean
