Yes, I was thinking along the same lines, but because I don't have permission to work, I thought they might accuse me of working here, which of course, as you say, I'm not.
I'm a temporary resident through marriage and have a hobby website that is registered in the UK and it has Adsense and Amazon ads so I can use the images. I have never been paid anything from these. Both accounts show a tiny unpaid amount sitting there which I only just became aware of. I'm retired and don't pay taxes anywhere. Will those ads get my website labelled as a business in Mexico which means I'm working? If so, I'll delete them.
