Are all these comments negative and also Space was do you mean by depends?
Well at this point, new clans aren't normally used aside from well established users making up joke groups. If you were to go and make a legit clan right now you'd need a decent layout, an interesting group idea or theme, at least 3 other users, proof of completed projects, and some kind of logo.
Arguably the most important part would be the clan topic layout, where as it's quite easy to pick out subpar clans based on their topic layout.
Some clans resort to building their own website.
Making a legit clan is not easy.
