Hello Group
You don't have to worry about this idiot (Hex3D).
From many people, I received messages such as Hex3D wrote to them: in which it was written that I am so and so, then that they have already started the court process, then that they have a person in the Telegram company, then that they will write a complaint me in the intellectual property system, etc. His last letter was: He blocks on Patreon, and that every time he will block on Patreon when is distribute the files.

This idiot is incompetent and stupid.
All his works violate copyright
The most he can do is block you on his site, but that's not a problem, I have access to his site at any time, and in the future you can download his models on my telegram channel.
Patreon or other online resources (marketplace) does not provide the personal data of client to the authors, therefore it does not have personal data about you (paypal or bank card). That would violate the personal data law

You can write back to him, and send it in all 4 directions.

And for the idiots who support this idiot in this group:
The system for detecting files or especially images, UUID, which is hidden in the Metadata of the file or image used by this idiot(HEX3D), can be modified. And I do this every time.
To copy/paste the tracking data from one resource to implement it in another, this is very easy
