I honestly wasn’t watching closely enough to say, but Beehaw’s admins/mods are particular about enforcing their rules, and these don’t require an escalation to actual harassment to be in violation of them if I’m not mistaken.

If anything they would prefer to be proactive and prevent such an escalation if possible, but this demands more active moderation (i.e. trying to talk it out vs. reactively banning), especially given Lemmy’s current barebones moderation tools, than their team could keep up with with the influx of new folks.

Given better moderation tools, and user tools to filter posts & block domains/instances themselves & the like, they’d be more open to linking with world again.
