There is precedent for Clubs banning supporters for tweets Beetle.
Leyton Orient (2021): 3 year ban - racist abuse of England men’s team members after 2020 World Cup.
Portvale (2021): indefinite ban - racist abuse of a Leyton Orient Player.
Preston (2022): lifetime ban over what the headline describes as “derogatory” tweets about the Royal Family, but included (tagging in the Club) a wish they’d all die en route to the late Queen’s funeral; accusing the late Queen of being a Nazi; & announcing plans to boo during the minute’s silence in her honour.
Chelsea (2023): lifetime ban after a conviction for a decade’s worth of antisemitic abuse directed at another supporter. (Presumably he wasn’t only antisemitic about the one Jewish man in question; but that abuse was what he was tried & convicted for; triggering first a suspension during the investigation; & then a ban).
While it’s at a Club’s discretion to some degree, it’s usually in reaction to racist abuse surrounding football. The outlier Preston case will be because he was tagging the Club in & threatening to cause disruption. (We also don’t know what else may have gone on.)
So banning-for-tweets has been happening for a few years, at least; but clearly in this instance it is egregious they have done so when the case [that should never have been opened] was NFA’d. I can understand having to suspend her when she was under police investigation if, & only if, advised by the police of it. But this is simply abusive; & as a PP pointed out, rainbow-washing with a side order of misogyny.
