@hipsterelectron It does individual deletions, but it's implemented in a buggy way and sometimes fails.
@hipsterelectron It's racy, it can fail if you delete a post before it gets bridged: https://github.com/snarfed/bridgy-fed/issues/1361
Other than that, it should work and it has worked for me in the past. If it doesn't, that would be a new bug.
