In the sensitive "personal" tab on your contacts, it is possible to blacklist contacts you wouldn't want to include in a future event.
These persons remain contacts in eContact, but you may also find it useful to deactivate them.
To find them again afterwards:

- In the default "Easy Filter" select "UnwantedPersonFlag" under additional fields
- Add the value "Y" to search for blacklisted persons
- Press "Apply" in the upper right
