Indeed, an integer is divisible by 3 if and only if the sum of its digits is divisible by 3.

For proof, take the polynomial representation of an integer n = a_0 * 10^k + a_1 * 10^{k-1} + ... + a_k * 1. Note that 10 mod 3 = 1, which means that 10^i mod 3 = (10 mod 3)^i = 1. This makes all powers of 10 = 1 and you're left with n = a_0 + a_1 + ... + a_k. Thus, n is divisible by 3 iff a_0 + a_1 + ... + a_k is. Also note that iff answers your question then; all multiples of 3 have to, by definition, have digits whose sum is a multiple of 3

I tried it once a few years ago and it seemed to work fine enough for me. I can't say how exactly it works now, but there is (or at least used to be) a free plan with limited functionality, so I figured it might be interesting to you

For Meet, I'd also suggest Jitsi. For Drive, I'd recommend giving cryptpad.fr a shot; that seems to be the closest to Drive's file editing capabilities.

Just to add, some also theorize that new elements may turn out to be stable, sort of the reverse of how f-block elements are a bunch of unstable elements in the middle of more stable [d-block] ones. If that is indeed the case, we may find a lot more candidates to work with in, say, materials science.

That wouldn't make sense either, because the user literally has to provide them all kinds of personal information in order to register. And no matter which IP address is being used to register, the user still has to pay to even use their service. So rejecting accounts simply because the registration was done via VPN is, in the best case scenario, overkill.

Don't get me wrong though, I have nothing against them; I just don't think their anti-spam measures are anywhere as good as they need to be, and their responses towards people complaining about them indicate that they wouldn't bother trying to make it better.

I get the reason behind it, and support it too, but it doesn't make a good impression when your account gets rejected despite every information being correct just because you signed up using a VPN (I can't verify that VPN is the reason, but it has been suggested elsewhere to be a cause for suspicion on their part).

I tried them a couple days ago, got to setting up Hetzner API, had my account rejected a bunch of times, found out Hetzner team is infamous for rejecting new accounts and cancelling old accounts by the whims of their 'protection systems', realized the only other hosting option supported by SelfPrivacy is Digital Ocean, noped out of it all

It'll get more complex than that. I'm no expert, but I'm guessing you have to consider the depth of the crust at your location, type of soil and the distance from (and time since) the last closest volcanic eruption, possibly distance from the nearest tectonic boundary, maybe even tidal forces (assuming they have a considerable impact on magma being pushed out, but this may be a bit too far)
