Federated comment removals? Does Sync handle them?

Despite removing comments hours previously, I'm getting complaints from sync users that they're still seeing the spam bots that have plagued the lemmy today.

This leads me to believe that sync for lemmy fails to handle federated comment removals (note: some instances, those running kbin or mbin don't handle them at all)

Can this be added to ensure that when a mod removes a comment, the comment isn't seen by sync users?

Thanks
