What you were expecting to happen, and what actually happened?
I was expecting to be able to report any player without having to submit a ticket in 4.3. However, once a player places you in his/her block list I think it’s no longer possible to access their profile, and thus to submit a report on them…
What are the steps to make it happen again?
Get blocked by a player, then attempt to access their profile.
Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
