@waverly you should be telling this to the moderator not commenting here and making @Maddy5768 feels guilty for making this pattern. Plus if the pattern is accepted that means nothing is wrong with it since the moderator have checked it before she/he accepted the pattern.
@waverly seriously tho, on this site, logos are't considered copying. There's quite a lot of different Instagram logos, but guess what? None of them are deleted because each logo is a different resolution plus none of us on this site designed the Instagram logo (that goes to Cole Rise). The same thing is applied to IKEA. This is a higher resolution, meaning that it's more complex but refined. Some people prefer refined but bigger patterns, while others prefer smaller and simpler ones. There's a difference between copying and having similar ideas.
