There should be no delays in accepting notes, but in the last days we got several spam attacks and many relay tried to filter them, so this may have generated some rejections.
I suggest you to use a client that fully support the Outbox model, pick up a couple of public relays and a paid one with a good spam protection, to try to be visible to those using WoT relays.
Next step: run your own relay.

If can be useful:

My current relays setup:

- Chronicle relay for inbox/outbox/dm and backup all my conversations
- Wot-relay to access my social-graph notes
- Pyramid.fiatjaf.com as secondary WoT relay + OpenTimestamp
- Nostr.wine to let flow in events outside the WoT with a good spam protection
- A couple of big relays (nos.lol, damus) as outbox relays, without announcing them (Gossip feature)

This setup, together with clients that support the Outbox model (mandatory!), is working extremely well, zero spam, snappy clients and low bandwidth usage.

TL;DR; The Outbox model plus some WoT wizardly, wins
