My server is set to not visible to the community because it is for my friends. I put it up and one of my friends sent a photo of a thing named Netflix in the chat that said "Watch this video to gain an advantage" that popped up as soon as they joined. Pretty sure it was a link. Not a huge deal, but I just wanted to know if anyone knew anything about this? Just wanna make sure it isn't an issue.
