1. I register as substitute for a tourney or team match.
2. I am offered to play with person X with skill level Y.
3. I accept and start playing. And then I realise that person X is on my ignore list.

I find this annoying. There are several ways to resolve the situation.
Either: do not allow proposals from ignores.
Another: show partner's profile at step 2.
Alternative: add the relation of friend/normal/ignore at step 2.
