Seriously, what do you think about the fact that this community page is full of "sexy girls wallpapers"? I think it has nothing to do with Linux, Arch, etc., and until proven otherwise, Manjaro Linux is just a free Arch Linux operating system and community.
Excluding the fact that this kind of stuff is terribly sexist and can lead to harassment behaviors , if you want to see/show sexy girls pictures, I believe you should go on a dedicated place.
Take a look at the Arch Linux G+ community, I don't think you will see a lot of these things.
Sorry for not being fun, but I'm pretty chocked by this, other communities have very strict code of conduct about this.
