Yeah, the possibility that this is someone being doxxed is something that’s bothered me as well. I’m not sure what the objective would be, to get the person pictured in trouble with their school/employer? Incite others to call and complain about them? The photos and details given aren’t particularly embarrassing or something that would whip up a mob, which is why most everyone is just confused about it. Maybe I’m missing something obvious.
Some doxxers will share personal information in a way that looks innocuous even though their intentions are not good, since a portion of the definition of doxxing involves sharing that type of information with malicious intent. Perhap by repeatedly spamming the Fediverse they are hoping that people will unknowingly take their anger out on the person the accounts are impersonating by contacting her workplace.
There's also still the possibility of it being blackmail. "Look, I've just shared this photo this time, but if you don't do what I say, next time I'll share more"
Same. If this is the case then they seem particularly obsessive given the sheer number of accounts they've made along with their time spent spamming so many members. The workplace mentions could be a means of inviting harassment.
I feel weird for even having to bring this up but to add on to what you said, another member mentioned one of the Nicole accounts posting a picture of a buttplug, and in the reflection there was an old white man who was bald. When this was pointed out, the Nicole account in question deleted the picture.
