I haven't watched the documentary yet. The one video I saw, on a porn site (and also on some mens rights incel site that linked from it), where you could enter her full name to pull any videos up and one, and only one came up, shows somebody having consensual sex, briefly, with one man while other men are surreptitiously filming her. The one man can see as he is facing the phone cameras that are filming them.
Everything I have seen and heard (never heard from her directly) is entirely consistent with her account. She had consensual (and pretty joyless) sex with one man, to keep him happy as he was pissed off with her for talking to other men (a situation I vividly remember from that age). It then appears that his mates burst in, either with or without his knowledge , but he certainly didn't seem to try and stop them in the clip I saw. This again seems entirely consistent to me with them then having forced group sex with her and inflicting various injuries, as you'd expect. So it seems very consistent to me that any footage (there were multiple boys filming in the clip I saw so could be more from different angles) that shows her "enthusiastically enjoying consensual sex" very probably were taken before she was raped, without consent, by different men, sustaining injuries as you'd expect around forced sex and becoming in pain. It also looks very much like it was a planned set up.
I find it hard to see how anyone can't see this as being entirely plausible and likely to have been what happened. Far more likely than a 19y old girl who isn't a porn actress, agreeing enthusiastically to rough sex in a claustrophobic small room with 20 odd Israeli boys that she barely knew, alongside a boy that she thought she was seeing.
