I keep getting a bunch of signups, and they post jibberish posts (often meaningly random junk) that go to my review queue taking my time and DB space.
Is there something we can do? Maybe recaptcha will help? For example require recaptcha on login, posting, and commenting?
If they are actually human spammers copy/pasting jibberish (why would a human do that?) maybe a recaptcha will make them think twice about their time spend.
