Munchkin code for the different websites

[Daniela_Bachman]

Hi Sanford, 

Thanks for the explanation. I have inherited a Marketo instance and have discovered none of our websites have the munchkin code on it. 

In scenario 2

their activities on *.example.net will be tracked to their lead in Marketo, but their activities on *.example2.info will remain anonymous and will not be shown alongside their lead in the database until such time as they associate themselves (or are associated via API, but that's another matter).

If they ever associate themselves with the duplicate anonymous activity, will this overwrite any existing activity that we may not want to lose?

No, nothing is lost, the anonymous lead and the already known leads are merged.
