Another website is using (by mistake, I guess), our GA code, so we're getting all stats of this website in our Analytics.
I noticed that two days after this website started to send its data. I set up a filter to only include data from our host name, and we're contacting the owners to warn them.
But now, is there a way for me to hide (or delete?) these entries from my Analytics? I cannot succeed finding a way to achieve this with data already recorded.
