Why did they get through in the first place?
Just to answer in regards to rotations before the algorithms on the site.
1. Algorithms didn't have rotations on all them at first when I joined the site; some did and some didn't. So I chose to make the site uniform. Since doing the inverse algorithm to get the angle of execution can get annoying after a while if you are trying lots of algorithms, especially when you make mistakes, I chose to keep rotations. Having rotations just makes messing around with the algorithms easier.
2. Sorry that all case groups do not have rotations applied to their algorithms
yet.
(i.e. ELL, COLL, a few PLL maybe more) are some I still have to fix. I am in school and have zero time to do any work with the site; barely any to even cube.
However, I will be fixing ALL the algorithms on the site after I am done school and leaving in my new city; will be adding more case groups as well.
3. In the mean time, I am checking submitted algorithms and approving correct ones after I confirm them by hand. If an error is made, I just fix the algorithm and resubmit it myself. I deny algorithms that I can't fix, that do not have rotations to show angle of execution, and that have AUFs.
