The thread has been hidden, yes.
To give a quick overview:
The member in question violated the Concepts Forum Guidelines, for which he was warned.
The most egregious of these violations was taking other users' work, making small alterations, then posting him as his own. When he was confronted about this by other members, he admitted the work wasn't originally his (which doesn't make it OK).
When I discovered the violations, I locked the thread and issued the member with a warning.
I then received a PM from the member, asking me to re-open the thread. At this point, I asked him to read the Concepts Forum Guidelines (which were linked in his warning) and to circle back if he still had questions.
The member continually went back to their admission of stealing logos as making it OK to steal logos.
I then wrote a detailed response to the member, indicating why one of their designs (which made small alterations to a logo a user posted on Dribble) was not in line with the Concepts Forum Guidelines. In this response, since the designer had claimed their skills were strong, I also gave advice to stick to jerseys, fields, etc. for already existing teams OR to focus on designing one individual logo and seeking feedback, trying to improve it. I also noted that there are potential legal ramifications to the member's actions.
The member continued to dispute, indicating that they did not believe they were guilty because they did not know the rules, though they had previously posted on the forum, "just wanted to make this clear so nobody yells at me "you copied this"or "this logo is already in use" or stuff like that."
The member also offered to send the moderating team the files for subsequent teams that were to be featured in the series for their review, indicating that these teams would be in line with the Concepts Forum Guidelines.
When the user sent three of those designs to the moderating team, only one was in line with the Concepts Forum Guidelines. Further, the member claimed that the designs, all of which were based off existing logos in one way or another, were "100%" theirs.
After further PMs, it became clear that no matter how many times the moderating team reinforced the Concepts Forum Guidelines, the member did not understand them, and more importantly, did not see their logo theft as wrong.
I think it's important that the moderating team on this board takes a hard-line stance toward those who steal other peoples' designs. Fundamentally, this is a board of people who enjoy graphic design and its application to sports, and content creators must be protected. On a personal level, it was the inability for this member to see why stealing logos was immoral, and the continued insistence that they should be able to continue to do so, that led to my vote for a permanent ban.
