Those are probably his "BDSM daddy" signs, a very botched attempt at erotic asphyxiation. He has tweeted about it multiple times, and they even made a video talking about their daddy/baby relationship, which implied mostly punishments for Taylor. A few years ago he sold on Poshmark padded BDSM restrains. Both of those stupid cunts always made a big show of how Greg would leave bruises on her during sex.He's almost certainly beat her. She had pretty clear choke marks on her neck in her "My hair transformation" video from 2018. I don't really want to watch more of her videos to find more examples but I'm sure that's not the only one
Sexual abuse has always been one of Greg's favourite ways of abusing his partners, after all.
I'm still of the idea that he pushes her around and grips her arms, rather than straight up beating and chocking her.
If you look at these pictures, in the first one the bruise looks like it comes from being held too tight, while the others seem to come from her "stumbling" and "accidentally hitting" pieces of furniture.
