I know Faye and Charlotte are both legitimate DLs at DiaperGal. Apple at AB Dreams is ABDL and only works with true ABDLs. Adriana at diapered online is a DL who wears 24/7 most of the time. Odetta Delacriox is a true DL. There's AllyCakes and MissPanda on twitter who are true ABs, both have modeled for sites before. I know from a conversation I had on twitter (I have a vanilla twitter account) that Chloe Toy genuinely likes the diapers, but wouldn't consider herself DL.
And may I ask how you actually KNOW those things?
Starting with the ladies usually fake "stage names" to the respective identities... it's a bit like with the boulevard press... not everything you read is the truth.
I am not saying, there are none who enjoy it... but I guess it's far less prominent than even you depict it.
It's something that I believe is done to add to the value of a fantasy... to make it more authentic... and that does SELL.
I have no problem with porn of most kinds - but I don't believe in the interviews etc... I guess it's just "marketing" if you get the drift.
