Wow... nice piece of investigative work-- well done! It's pretty disgraceful what these people are doing. I am not even sure whose "department" this is, since it's basically someone exploiting a loophole in a service and getting something for nothing. Did you message @fyrstikken directly about this?
This seems to be some combination of spam and fraud and possibly "post farming"... @patrice, do you want to look at this one?
I would say it's the responsibility of the owner of @booster in this case, as it's his bot being exploited. I haven't had any contact with @fyrstikken, if you could send him a message with a link to this post for his eyes to see it would be appreciated.
