Vote brigading matters. If you're subscribed to a 'controversial' community and every post gets downvoted to oblivion, you and other subscribers who sort by 'hot/top' won't see the post unless they go directly to the community.

This slowly kills the community, even if its users are active on Lemmy.

I'm not. I only care about it at times if I'm not sure if my edgy joke lands right.

The problem is, here I want to stay anonymous. If I share an unique meme from c/risa on some other network e.g. discord, or even phone number-attached TG\FB\IG\whatever, reverse image search and then going to the upvotes makes it easy to narrow it down to who I am here. Easier, than watching packet sizes of said images via ISP or breaking into my phone\PC, and it can be done without any paperwork.

I'm yet to say something worth a notice on this or other accounts, I haven't shared secret schemes of warplanes like they do on WarThunder forums, but I'm very dissatisfied with how my state's doing, and there are laws making my critique a criminal offence. Yeah, right, they are this fragile. It won't stop me, but it concerns me that we, as Lemmings, think it's not that public, but kbiners see upvotes, instance admins see both, and a federated instance by your local CIA-thing can vaccuum it into their database once federated.

Compared to Reddit, Lemmy is better. But while Reddit needs to accept a request from authorities before giving up this aspect of one person's internet life, Lemmy requires a pretty simple data-mining server, and it'd suck in everyone's history.

I think it's inescapable with all this federating stuff. But it is a thing to keep in mind.
