Hello. 
We’re a web development agency and are using matomo for a customer to track certain actions a user performs on our customers website. When a user is performing a certain action, an event is fired and a goal conversion is triggered.
One of the actions that we’re tracking is if a user has sent a contact form, which is very important to our customer.
Unfortunately, one of our contact forms has been abused to send spam and therefore a lot of events / goals that don’t hold any value have been triggered and are now showing up in our reports.
We do know exactly which events / goals have been triggered by a spam bot and would therefore like to remove those from Matomo so that our data is “clean” again.
Does anyone know a way to remove those events / goal conversions?
Your help is greatly appreciated.
Best regards from Germany,
Paul
