So far, we have a captcha on account creation now and it seems to be working (from what I’ve seen, anyway)
It’ll be a tough balancing act though. Relatively frictionless sign-up has been great for us, and anything that deals with bots will also affect that. Whatever else we may end up doing will need to be carefully considered.
