The fact that you've never participated in a signature campaign is definitely in your favor.
Though, that also makes it completely ludicrous that someone plagiarized using your account...
What benefit does it give 'you' to plagiarize when it's not to increase your post count for a signature campaign.
That is an outstanding question. Here's my best response:
So of the ~5 people that had access to the account, some have vested interest in the company, some were paid by the hour. The person that committed the crime, by no shear coincidence, was one of the people paid by the hour.
My best guess as to why this happened was so they could probably bill for work they themselves didn't do. For example, if they were billing 20 minutes per post (this is a totally random statement, by the way, not reality), they copy/paste a post that takes them 2 minutes, bill for the extra 18 minutes and save the rest of that time and go watch some Netflix. I do think this was a one-off as they started their work though but I could easily be proven wrong.
Literally the only job description was to be helpful and not spam. To me, the whole process has been mind boggling. If I/we had been a less helpful person to the community, as >95% of new gambling related accounts are, we could have just created an account the day we were ready to launch and launched and been done with it. Instead, we're grossly penalized for trying to be an outstanding member of the community initially. That was the entirety of the goal of the program as you asked. To start off with a good reputation rather than nothing. It's been heart breaking so far and I'm doing my best to make any amends so far... Hopefully that all makes sense.
