I know that as leftists, participating in online communities requires a certain level of discretion. I’m admittedly not as privacy focused as I probably should be, but I would like to at least minimize the chances of being put on someone’s list. Do I need a VPN every time I open this site or do I just need to be careful of what I post?
It depends where you live. Some countries have stricter censorship than others. Unless you are making some extreme calls to actions or what might be construed as a threat you should be fine.
I’d like to think Lemmygrad’s operators keep their connection logs fairly well-protected, and store as little user data as possible.
I’d honestly be more concerned about opsec (operational security). For example, you might post in an apolitical thread about how you live outside of a city, you work at a local coffee shop, or maybe your username is “redcarowner69”. There’s three facts about you that someone with too much free time (or nation-state funding) can begin to arrange.
Just don’t post personally identifiable information about yourself.
Did not expect to get so many answers so quickly. Thank you all.
