I think she was probably teased, like most of us were at that age. If she behaved anything like her self-insert 'Erimentha', I can imagine that she probably had it coming. Not that any child should be treated unkindly, but its kinda just what kids do. Especially to a know-it-all little tit like Erimentha/Hermione-types.Yeah, I don't believe for a second she wasn't bullied at all. She has such glorious memories of high school that she's spent every ounce of energy since trying to turn herself into a 12-year-old schoolgirl again and recapture the joys of having private school teachers who were paid to tell her she was special and gifted tell her she's special and gifted, despite her being a talentless dunce.
Her stories of being bullied have never added up and never stayed remotely consistent. It went from 'I was navar bollied, I johst have an interest in the sobject' to 'I remambered! I WAS bollied! I johst didn't realise it at the toyme! Please buy moiy bohk about me being bollied!' to 'I AWHWHEYS knew oiy was being bollied!' and from "Oiy was bollied in Yaahr SAVVAN" to "Oiy was bollied in YAAHR NOINE!" to "OIY WAS BOLLIED ALTERNATE YAAHRS THROUGHOUT HOIGH SCHOOL, BUT ONLY ON WEDNESDAYS AND FROIDAYS AND ONLY IN THE SPRINGTOIYME!" to "THEY BULLIED ME SINCE BARRTH!"
She could never provide a concrete example of anything that happened to her beyond people just not wanting to be her friend or people offering constructive criticism online, and every time she spoke about it, there were new inconsistencies and even stupider out-of-touch advice and it all sounded even less believable. There's a reason she had to delete once of those videos due to overwhelming backlash.
If she experienced bullying so severe that she made it the defining trait of her identity for several years, she wouldn't have forgotten all about it until she'd started reading lots of bullying books and decided to write her own. And she wouldn't want desperately to relive her school years or go back to spend time at the same school she was apparently tortured and tormented for years. It's all horseshit. She made it up.
Erimentha Parker was painted has her actual experiences with bullying, yet was trope-filled drivel where the bullying was so bizarre that there's zero chance it happened in reality. It also showed Erimentha/Ruby to be an insufferable, judgemental, self-absorbed, spoiled, antagonistic little tit, which Ruby painted as admirable qualities, shedding a lot of light on why nobody would want to be friends with her.
She just really loves the narrative of someone being such a gifted child prodigy that all the other children were so jealous that they bullied them for it. She's seen that in lots of simplistic kids' stories growing up and mummy likely told her how jealous everyone was whenever Ruby threw a tantrum, so she's just adopted that narrative for herself.

*Yeah, I don't believe for a second she was bullied at all.
For children who like to tease and call names, they had a lot to work with. Ruby boobie, Bones, Lazy Bones. And her response to the teasing, I bet it only encouraged them. Again, I don't condone children being unkind to other children...but I was a kid once and was on both ends of teasing. I learnt pretty fast that if being teased, how you respond can really sort it out fast. (not victim-blaming here either). There is a huge difference between bullying and teasing.
