I don't know anything about the allegations, but PSL's form of party discipline is definitely conducive to abuse. They monitor members' public statements including social media in order to police their rhetoric. They also put intense pressure on members to participate and mobilize. One comrade in the Boston branch was hospitalized in in-patient and then bullied for wanting to step back when they got out.

I think a social media account that targets a particular org is completely sus. Honestly, even some "tankie red fash watch" account that targets ML orgs is less sus because you could at least explain the tankie watch account as an overzealous ideologue who doesn't understand what primary contradictions are. This sounds like the work of a disgruntled ex-member or a wrecker.
