Captcha or similar for new user registrations... how to delete accounts that have never logged in.
Sorry if this is somewhere obvious, I have looked around admin options and I cannot find anything.
It appears to me that someone is using my server to spam people with registrations. I think this is happening because there are many registrations occurring every day (not a huge number, but around 5 or 6 every day) that never log in, and when I track down the registration email it is being bounced saying the user is receiving too many emails (which leads me to believe my server is being used in some kind of automated spam process to overload users emails). Since I usually only get a few valid users a week registering on my server, I am relatively certain these are not valid new users.
Is there any way to turn on a captcha or something similar to cut down on these bogus new user registrations? Is there a way to purge the database of all of these bogus accounts? It makes looking through the valid accounts that have actually logged in quite unwieldy.
Thanks for everything you guys do, hubzilla is amazing as always.
