I've been playing both FS and CS for weeks and never ever felt the need of that. I've great neighbors and they've always been so nice to me. Users in general have always been extremely nice to me. That's remarkable and not so common at all over the Internet. But tonight I've stumbled upon (well, actually he/she stumbled upon me) some user with very inappropriate behavior. I'm a grown up girl, so I don't really mind, just had a couple of laughs, used to trolls and alikes. LOL But that led me to think that maybe a block function for certain users would be useful. Also... PMs. This is a social game after all, right? So... If you've the need to really *communicate* with some user, either than "ntc ntw cyc cycb" and stuff like that, how could you? You can post on the wall, yes... But it will end up to be messy at least.
Sorry if it was posted before.
I checked but, if so, I missed it
P.S.: That's equally related to FS and CS, of course!
