@mark-coniglio I like Stop Forum Spam. Free is not always good, but in this case it is. Nothing will be a magic bullet. Layered onions, etc. Google is evil so I naturally prefer hCaptcha.
Cool. Has not been a big issue for me (most problem accounts come from gmail, yahoo, hotmail, etc. - shells hidden w/in shells like Russian dolls) but it is an election year and I expect things to become increasingly nasty for community forum sites. Thanks for the tip. 👍
