Hi,

If a remove a target that has a alert in firing state, alertmanager sends a "resolved" alert to ours receivers.

How can I prevent that?

That's expected as the alert is no longer firing.

If the target is removed from the scrape config the alert will resolve anyway. If you want to persist the alert set send_resolved to false in alertmanager.
