@chris I guess I've been very lucky (or just don't use it enough yet). I haven't been hit by any spam.
According to Ars Technica, there has been an "onslaught of spammers". Oye! At least the keybase folks say that they are trying to do something about it.
@kcoram for me it's just the spam but I've also seen many women complain about how toxic the platform is.
