Where Does the Spam Come From?
Unwanted entries are usually created automatically by your cloud calendar provider rather than your local app:
The Gmail & Google Calendar Link: By default, Google Calendar scans your incoming Gmail messages for invitations, flight bookings, or event confirmations. If a spam email bypasses your regular email junk filter, Google automatically puts that fake appointment right onto your calendar feed. Because aCalendar displays what is inside your phone's database, these spam events show up in our app too.
How to Block Calendar Spam
To permanently fix the problem, you should change your settings on the server side. You can read more about how this system works in these external articles:

Because this issue has been known for many years and large providers have not fully resolved it, we added our own safety features:
Our Custom Spam Filter
Starting with version 2.2.4, aCalendar includes an internal spam detection feature. This filter scans for common junk entries and automatically hides them from your views so they do not clutter your daily agenda.
