Just getting off our main issues of the moment, let's look at robo-calls to your phone [and/or texts]:
Methought the way to go was to entirely rethink our relationship with anyone else out there. I would list those I wish to hear from or receive something from as:
1. Close friend call or text or email
Thus these people are not blocked in any way and are part of my mobile phone's address book, the phone only accepting calls from address bookees. That's not difficult to set up.
2. As part of that, disconnect the phone from the wall socket
I have a splitter there so one half goes to my wifi hub, the other would go to my landline, were it connected. Very occasionally, I connect it to authorise something on a on-off basis.
3. Others I've allowed to my text or email
This includes the boiler engineer, the NHS, other branches of govt, those I do need to connect with and prefer it not by phone.
Now, if they call and they're in my address book, e.g. the GP, then they get through, which helps with phone consultations. Some people don't like these but I do, as they allow me to stay away, physically, from the GP and remain isolated.
4. The blog
You all already know how that works.
5. The postbox [mailbox]
Not a lot of control over that, I check every few days and sort it out.
Contrary to popular perception, given the current state of play, I have a good relationship, personally, esp. with YouTube, as I use their products fully and abide by all the rules. It does help with the blog in that they tailor videos, for example, plus advertising I do wish to see. So that actually works well.
The whole rationale is that I do not wish to be contacted cold. Full stop. Period.
With some people in the close category [N1 above], it's wiser to keep it to email so they cannot be traced otherwise. And even in our conversations, we avoid certain details.
Hope this might be of some use to you.
