Okay guys, firstly I want to say big thanks to everyone that took the time to explain how the Forum works. I haven't been in such a forum in a while.

This is the post i'm talking about : https://ninjastic.space/topic/5427627 (topic id: 5427627).

The guy came to our Discord attracted by our small rewarding game we have currently going there and asked how to play about a week ago.
After receiving an answer but not winning any price (meanwhile his friend that invited him did twice), a couple of days later he decided to ask how to sell the reward and make this offer.
Here is the full chat:

After he offered to make his post, I told him to hit me up in DM and I will provide him with all the descriptions and graphics he needs.
If needed, I can show the full chat there, but he already deleted some of his messages. We never agreed on payments, but after posting the post, he dropped his wallet address.
After i told him that I'm not going to send him anything since his post didn't reach anyone, he started publicly trash talking in our community.

but also trashing under our linkedin, reddit and even dm'ing members of our community. Even marked himself as project manager on Linkedin:

We are currently still discovering such posts around different groups and communities and try to report them all.

I hope you guys understand my frustration and why i want to share the situation.
