For example:

There are photos in that thread that are allegedly of the poster, but those photos belong to a different Reddit user that has gone by several usernames. Currently, that user posts as /u/awhha (she posted as /u/6mmshhh9 before and had other names before that). awhha deleted those pictures years ago, presumably because they showed her face. awhha is not the same person as aryaisthebest, their writing styles and life stories don't match up. awhha is currently in college, but aryaisthebest claims to have left college years ago.
Plus, going through aryaisthebest's post history on reddit, a lot of them just aren't plausible. One of them involves a masseur giving her an unsolicited "happy ending."
Another thread:

Some user already called this one out, but the thread was never moved or moderated in any way.
Generally, I'm skeptical of most threads posted from a female perspective and catering only to male fantasy, but you're right, I couldn't prove all of them fake. I'm not sure if these threads give off the wrong vibe to anyone else. Maybe other people don't care or would rather not know. I made this post out of curiosity as to what others think.
