Maybe that was the case when Lolicon first became a thing, but these days loli/shota exclusively refers to body type, hence why literally every hentai site that has those tags apply them to all characters with the body type and not exclusively to underaged characters or those with childish personalities/presentation.
Yes there are plenty of people irl with petite body types, that's irrelevant here since loli doesn't refer to real people, using the term to refer to anything real is super weird.
They do that specifically as the line for legal regulations. Don't confuse utterly removed policy for what the fetish or whatever actually is. This site is the perfect example of that. Their use of futa/trans tag is in fact pretty different from lots of other places.
Most places that have policies against this kind of content are simply treading on the side of safety by banning anything that looks like it could be shota/loli, because they deal in porn and combining the two is all anyone will think from the outside looking in. On top of that, the sites themselves ofc hardly want to deal with confirmation nor do they care all that much. If it looks close enough then it's good enough to ban. Not only does that make sense, I agree with it as long as they're consistent about it.

A lolicon (and a shotacon) is Japanese slang once exclusively used to refer to real people who are pedophiles, especially given Japan's long-standing problem with joshi-kosei which you've probably seen called JKs in porn . JKs and the like are sadly an even bigger problem in Asia today, so the victim slang (loli/shota) is still used to refer to real people, sometimes as a pretty disgusting joke but sadly at times non-ironically, such as in the currently unraveling Kris allegations surrounding Mr Beast where Kris is being revealed as a monster.
The word bled into the western cultural geist along with tons of other Japanese culture as both their SFW and NSFW content spread and like a lot of slang it evolved to be used more widely. Just like various forms of sexual abuse and assualt such as blackmail, rape, coercion, etc, which is like 95% of hentai, shotacon/lolicon stuff in porn is usually portrayed as an unrealistic fetish.
You really should do more than drown yourself in porn, much less base your perceptions of the world on it.
Because
that's weird. I also never called a real person a loli or anything. What I was saying is that just because someone has a petite bodytype or are flat-chested in non-real media doesn't automatically mean they're a loli.
