Large number of probably not-genuine users

2661 Users in total

Many of these from looking at the Django admin page for opencodelists appear to be not genuine users ( slack thread ).

I'm not sure there's a robust method to identify these accounts that fail the "looks a bit dodgy" sniff test, but here are some possible heuristics:

E.g. 89 are from .ru domains, 1132 have spammy phrases embedded in the username part of the email address split by many . characters

>>> len([u for u in User.objects.all() if u.email.count('.')>4])
1132

2081 have no codelists associated with them

>>> handleusers = set([h.user for h in Handle.objects.all()])
>>> versionauthors = set([v.author for v in CodelistVersion.objects.all()])
>>> anyauthor = handleusers.union(versionauthors)
>>> len(anyauthor)
580

Start from the OpenCodelists admin User page and review the issue's proposed heuristics: email domains, repeated dots in usernames, and users without associated Handles or CodelistVersion authorship. Check the linked Slack discussion for context. Done requires an agreed robust method for identifying non-genuine accounts, since the issue does not define one.
