I actually think it's legit. Looking at her X profile, which I seem to have followed for awhile, she's been on X since 2015 and actually been posting occasionally over the last few years. Interestingly there are posts of her responding to people which appear to calling her appearance rather masculine. I originally thought she was MtF trans, not that I have an issue with that other than when people hide the fact for perseonal gain, but I actually suspect she's CIS female after looking at some of the photos and videos. I agree the photos look, odd. Almost like she's using a filter, but the videos are similar so I don't know. link text
All right, I think I was wrong. I think the reason for her unreal-looking proportions is that she's very short, but most of her images have no sense of scale so you can't tell. On her instagram there are some pics with non-dungeon lighting with another person like this; I'm assuming here the other woman is about average height, which would put her under 5 feet.
I do still think the "Alyson" Twitter account is suspect, but now I think it's just impersonation with stolen photos. Either way, "April (lil_giant_killer_)" is on the blacklist here so someone seemingly doesn't want her images here regardless of the account they're posted under
In my opinion, the pictures reek of AI or something uncanny.
I'm open to proof to the contrary.
