I have the following project for this. https://github.com/ahmetalpbalkan/goodbye It can DM you when someone unfollows you. But you need to host it somewhere.

tempting, but i feel that tracking who unfollows me would only annoy me for no good reason.

I made a thing yesterday to do just that. :)

That's a nice simple little script. Thanks for sharing!

No need to use git, since you can just use diff(1) to find the unfollowers between any two dates. I've been doing this for a while with a Go program I created[0].

Unfortunately, people who change their Twitter handles (which I found surprisingly common) show up as false positives - you either need to filter these out manually or match against the user id[1].

[1] Adding that as a separate field and then calling `cut -f2` would be a quick hack, now that I think about it.

True, but git comes with many tools (e.g. gitk) that make it really easy to the diffs-over-time of a repo.

that is a really great idea

Thanks!
