Submitting a profile picture has been set as mandatory on the join form for my site, which hasn't even launched yet. In less than 18 hours, I've had nine sign-ups, none of which have a profile picture. Not only that, but four of those have actually confirmed their registration. So either I'm getting pestered by some really sophisticated bots, or there is a growing number of actual humans who know how to render as useless what is supposed to be required.
Since setting a field as mandatory apparently has the same value as a plug nickel, I was wondering if a CRON could be set that would auto-delete registrations after a certain time if they don't meet specified parameters (e.g. uploading profile pic), parameters that could be changed periodically to help even more?
I don't know how to write such a command, but I'm quickly getting to the point of being willing to pay for that information as there are other things that I need to devote my time to rather than dealing with this. Until this is resolved, I've set registration by invitation only, but I really don't want to have to keep it like that.
Thanks in advance for any help!
