So I'm considering buying traffic for one of my sites and I know it will totally screw up my analytics for that site forever in the long run unless I can omit/delete "sections/time frames" of the graphs. Is it possible to delete or even modify part of my analytics? For example lets say I buy traffic today until the end of the month is there a way to omit that data so it doesn't mess everything up? I'm not entirely sure if that makes sense, but any thoughts?
