Lemmy does not have anonymous voting - https://lemmy.eus/post/182574

Each instance decides what to show on its homepage and its own moderation rules, so you are free to build (or find, if one already exists) an instance that attempts to prevent the kind of manipulation you are worried about.

No. It depends on their home instance.

A few may go out of their way to make it easy - there is nothing stopping a Lemmy instance from requiring government ID to sign up, after all. A few may go out of their way to make it hard - there is nothing forcing a Lemmy instance to collect any data about a user. Most big instances will probably be at the same level of difficulty as tracing someone from their email address - their servers are probably logging IPs and locations, which will be a starting point for tracing identities, but not guaranteed to be “easy” by any means.

I have worked on non-trivial (aka took 10-12 people over a year to even deliver an alpha) greenfield projects, where I literally made the first check-in into the repo.

The only 500+ line PRs I raised was auto generated boilerplate code, or renaming something.

I don’t understand the optimism of devs who spend weeks writing code without bothering to test anything they’ve written. Unless you’re writing utterly trivial BS, how does one have this level of confidence in their code? And if you did bother to stop and test, why on god’s green earth would you not raise a PR? Why wait till you have thousands of lines of code before asking for feedback?
