'I am only speaking from experience and wanted to let parents know the dangers out there'
You're not speaking from experience, you're speaking from a Daily Mail article. Unless one of the families in that article is yours?
'I wasn't intending to making it an agency v gumtree thread'
You might want to re-read your op. You know the bit where you said 'Parents please be very wary about looking for a nanny privately' or the title where you name Gumtree.
'you're right why should I declare my interests?'
Because it would be honest to.
This was nothing to do with Gumtree or private advertising. Trying to make it about that is ridiculous. I think your motive in posting this is clear. I expect agencies are losing a lot of business to Gumtree, what with it being a good place to find a nanny for about £20 rather than the hundreds that agencies charge. I think you're scaremongering and I think it's in very bad taste.
