Seems like you edited to remove the account part, that was a good move, this is my main, the other one was my old one that’s still on the phone.
Other than that, you’re right to call out the lack of critics from db0 admins/mods and general community towards tankies, but this is still a bad example to my eyes. We cannot blame someone for disengaging, especially a regular user with a good reason.
If i’m not mistaken, the very last graph showing posts by month shows a significant decreasing over the summer, or at least specifically july (since august is not over yet). It says June is around 12M posts and July around 9M. August seems already over 9M and we’re only 2/3 in, so maybe there was some drop around July for some reason, which could explain OP’s feeling.
As for the reason, i’m not sure, maybe a combination of factors like some server blocking access from UK with the latest privacy bullshit, some server having signficant downtime (i think slrpnk.net had a problem with servers locking themselves up while tech admin was abroad), and maybe non-Lemmy factors like holidays (though they don’t seem to impact previous years stats).
Securing persons (young children, elderly, or disabled people), pets, or critical objects (health related stuff, maybe a box with important papers or family belongings) can require a bit of planning. Also good to know where to head to once you’re out, especially for kids if fire happens when they’re alone. But yeah, for most people, “get out” is probably enough.
