which G might interpret as 'interfering' with the click-thru process.
I know what you're saying, but I cannot see that interpretation. "Interfering" I take, in the context of that clause in the TOS, as meaning "obstructing" or sending someone off somewhere else, or in an iFrame etc.
It's about tracking, and on that the TOS is silent. At the moment anyway (Macro's post refers).
