Regarding the online abuse in regards to being trans, same here. I had this problem on twitter GC / TERF pileons so shinigami eyes was quite useful to have. When trolls learn you're trans it's like low hanging fruit to them so I get what you mean with low karma accounts being blocked from engaging in a community

Lemmy is in it's early days so they may actually add an overall count with a similar safety feature in the future or additional safety features for communities to use. If the Lemmy devs don't create something to help with this then it's possible that someone might write a bot to help with moderation as automod and the likes were quite popular on Reddit. I'm speaking from my own experiences here but I find that over time as a mod or admin who is a marginalised person, you tend to become friends with mods and admins from other marginalised communities within the fediverse and get a headsup on who's doing the damage and where before the abuse is aimed at the rest of the community. The fediverse is currently mostly reliant on these teams for user safety so for now, connecting with other communities and talking to each other is one of the best tools we have until more features are developed.

Thank you for your response btw, it has made me think about what Lemmy might need so communities can keep each othe safe. Some Lemmy instances will tolerate abuse like that and leave it upto the mods to govern their own communities but we've never been a fan of anti-LGBTQIA+ hate or TERFs here at DATATERM or any of the other fedi spaces run by @revengeday@revengeday@dataterm.digital .
