For others who search for this question - the name typo wasn't a problem.
Additionally out of 6 flights around europe only 2 times I saw them use the bag-box near the entrance of the security gates ( they check if you have ryanair boarding pass there) Luckily they didn't check anyone with backpack (they rarely fit into the 20cm thickness).
I vote it to be the best airline for backpackers :-)!
