I see vague similarities, but not much beyond what you could normally expect with most similarly themed fansites or even just most forums in general tbh
There's alot of similarities in all of the fansites, and fourms for ac as a whole. I think we shouldn't judge them for looking exactly alike since it's pretty difficult to look anything apart from the vast majority of ac sites. we're all players, even in different communities.
While I don't believe you had bad intentions here, creating a thread that essentially does nothing but mock another forum isn't something we're okay with, especially when the owner of said forum is also a member here. There's nothing wrong with pulling inspiration from a site that you think is laid out well and making your own forum using ideas that you may have had as a result of visiting other forums. We're good so long as it's not a carbon copy.
