Over the weeks I've sent a bunch of messages, like offering mod positions, asking for things etc. and I get no responses to about half of them.

Sure, nobody owes me a reply, but I'm wondering if there's a different reason, such as:

1. Ignoring all notifications, because there's no immediate distinction between a DM or a comment reply

2. Using an app that doesn't support messages (which one would that be?)

3. Federation issues (when sending a DM to a different instance)

Thoughts?
