Hey Soma,
We see now, and we will get you unbanned so you can join and play.
You joined with what was seen as a rather negative, snarky attitude towards the players welcoming you back. While we were processing what you said, the filter caught mention of a mature rated video game and you were banned.
We do see now that the video game reference was the name of an actual game setting so we do understand that you were not trying to mention the mature-rated game it's self. Sorry for this misunderstanding.
You might still want to take it easy as far as things like telling the other players not to welcome you back- they were just happy to see a player join and wanted to offer up a "WB!" in the spirit of the Famcraft way.
We do have players of all ages and some of them become confused when their kindness and hospitality is met with what comes across as negativity. Thanks for understanding. We'll look forward to seeing you back on the server.
