Interesting, that is directly illegal afaik in many EU countries, where the rule is you must keep as far right as possible at all times. I.e use only left lanes when overtaking.

I think it’s clear that there are problems with children’s use of social media today.

But a blanket ban is not the way to go. Especially since it will most likely just lead to age verification and all the issues that brings.

Fair, I was not aware of that exception. It does seem to cover this case, assuming Google is actually not sending any data outside of the phone, use it for further training etc.

The person owning the phone where the processing takes place, is the processor of the data in this case. That still requires consent from the data subject per gdpr.

In many places call recording (or indeed processing of personal information which is highly likely to be present in phone calls) requires consent to be legal. I highly doubt this kind of processing is legal in the EU without both parties consenting.

The most important thing, if you intend to do outgoing email, is to get a reputable hosting service, where you’d have few/none bad neighbours. Unfortunately that often doesn’t come together with cheap, as cheap solutions often attract a certain clientele. I’ve also had more luck with slightly smaller (but still reputable) providers, i.e stay away from OVH / Hetzner and the like. If you want something cheap, it’d probably not be a good experience to self-host.

With my self hosted solution I have no concerns about deliverability, and only very few occasions had blacklisting issues (due to neighbours in the /16 range).
