Like said if the instance has basic autmation at least 1 is doable.

In the case of “DMs on removal of a post / comment” it is possible to do that with the current api of lemmy. But sadly nothing “official” yet. And it wont come anytime soon as lemmy devs officially announced they wont work at any moderation related topics for a while.

Sadly thats fediverse, instance come and go as they like. Because behind them are humans that do this in their freetime ( most of the time out of their own pocket ). Big respect to everyone hosting a federated instance.
