The minimum age is also what made me delete my account on the spot.

Such an overreaction to be honest. If you think it's wrong to meet up with people under 16, don't meet up with them. As for minors, don't allow them to meet people 3 years older than them if that's what you're afraid of, although it's still an arbitrary limit. I can imagine a 16 year old open to meeting 18 year old people, there's nothing wrong with that in my opinion.

Look, I can go outside and meet with 16 years old as an adult. Does not mean I do it and it does not mean I support banning minors from going outside, because they might meet adult people.

Note that I'm from a country where:

1. The minimum age for sex is 16.. Does this mean I approve of 16 year olds having sex with, for example, 26 year olds? No. Are they allowed to, according to Dutch law? Yes, if both persons are able to consent wilfully. Note that in order to be a prostitute or to act in pornographic film, you still need to be at least 18.
2. Online communication with a person of 16 or older with the intention of sex is allowed. I'm sure since is something that is of the main thing Alovoa provides, having a minimum age of 16 would be enough. I assume the creator is from Germany and I assume they have similar laws as the Dutch in this regard.
3. If you're a dad and you take your own child to the park, without the mother, you aren't seen as a child predator.

I'd rather have USA users disallowed from this instance rather than yet another service needing to accommodate for the prudish USA. The USA users could have their own isolated instance with their own rules. I assume USA users wouldn't be matched with European users anyways, due to the large geographical distance.
