Spam User to the Commumity Calendar
Hi: I’m sorry you’re facing difficulties.
When a user is not logged in (ie, if you accept anonymous submissions) we do add some anti-spam measures – a hidden honeypot – but, sadly, it’s not infallible.
If you’d like to see stronger measures in place then please post a suitable request, beyond that though you’d either need to implement extra anti-spam measures yourself or else limit submissions to authenticated (logged in) users.
Does that help at all or at least explain the current situation?
