if it makes you feel any better those aren't the actual names of my alters and some information is edited. i will try though.
i wouldn't call it feeding into them. alters exist whether you want them to or not. if you try to ignore them, they just become more persistent and soon enough you lose control. it's better to bargain with them and decide when is an appropriate time for a particular alter to be out and set boundaries with them, though not everyone has perfect (if any) control over when and where. relationships have to be mutually beneficial otherwise you're just going to fight. establishing equal ground is how you get good with your system and work toward intergration and less amnesia, so yes, embracing alters is encouraged. it's the only way DID gets better. i don't see anything wrong with child alters being on the channel but i also don't see anything wrong with keeping them off of it. they're kids and they should focus on being kids. not correcting decades of stigma. but if you allow people to see child alters doing what they want and the kids are cool with it, why not? it only provides more information to the general public and that's a positive thing as long as the child is happy and not being harmed.
alters develop accents because sometimes, stay with me here, they have have backstories or sometimes fit people's images of what certain kind of person should look like. Jo could be a white guy with blonde hair and blue eyes because that's what the Brain envisions a successful business man to look like. he could be a man because the brain believes a man is more desireable in a work place and less susceptible to emotional breakdowns. now, i'm not saying any of those stereotypes are true but people think that way. everyone has their own personal image of what something should. when you think of apple pie do you just see the slice of pie on the plate? maybe one person envisions it as a warm slice and another sees it with a scoop of icecream. appearances also change as these alters grow. just like how someone grows out of their emo phase and stops painting their nails black. Maybe Joe grows to be more of a laid back person a has a tattoo now. Joe does not see the physical body as his own because when he looks in the mirror it's not him that he sees. he knows how he looks and the body is not it. it rarely is for alters.
DID is so complex that in the mind there is what's called an inner-world. and in the inner-world alters look like themselves and do what they want. i could go on about this stuff forever. there is just so much to it.
also for accents, an alter could have an accent if they were formed in the place when that accent is found. you could be originally from new york and have new yorker accent but then move to georgia and happen to form a alter while there. techincally that alter is from georgia and therefore it makes sense they'd have a southern accent. but it doesn't always work this way. alters vary greatly.
finally, body dysphoria with alters is just like with trans people or non-binaries. a male alter in a female body will usually wear a binder or pack. but again this varies alter to alter.
I assume Chloe collectively made the decision with her system to do youtube. that is typically how big choices are made in a system. before you buzzcut the body's head, you're supposed to ask everyone and come to a compromise. but of course you can't always please everyone so those who are opposed either don't participate, give you a hard time about it, or find some sort of middle ground.
the thing is that if you watch some of her vids, when she has a switch, she is sometimes confused and other times not. it depends on who the switch is with and her communication with that person. no one is co-con with that many people at once. you wouldn't be able to hear anything anyone was saying if all 22 people were talking at once. it doesn't take co-conciousness to pick up a train of thought, just good communication because then there is no amnesia wall to make you confused. Chloe is closest to Kyle and if you watch vids where he switches in, you barely notice him popping up because he and Chloe are so close that the switch is virtually seamless.
alters have an image of what they look like because their appearance is tied to their initial role. If Chloe needed a physical protector, maybe that alter would see himself as a muscly lumberjack who's 6'5 because in Chloe's brain, that's her image of what a protector should look like.
Ages are determined in many ways. it could be literally how long that alter has existed, some alters age slower, some stop aging and then start again, some alters have actual birthdays. Age can also be tried to personal development. an alter can over a large obstacle and come other the other side feeling wiser and then "boom!" they age. maybe if a laid back alter is needed, they're formed as teenager who, at that age, doesn't take life too seriously. and they could stay a teenager for god knows how long unless they some method of aging.
so they don't look like Chloe. they have their own physical appearance and when they are in the body and look in the mirror, they see Chloe. when they are inside they are themselves.
